ASIO- Audio Streaming I/O

Peak is compatible with the Core 2 but not yet compatible with the MP-100. Compatibility of Core32 with Peak is under review.

There is a 47 ms latency with the ASIO drivers. It is possible to monitor with zero latency using Lexicon's Punch feature.

Pressing the Monitor button in the Reverb or Punch tab should make these items available for selection. Last reviewed: 11/1/99 Deactivated 4/3/00 - incorrect info and if corrected would be duplicate of release notes.

Installing Cubase before installing Lexicon Studio will ensure that the registry key gets created.

The Core-32 and Core2 cards can share IRQs. If you think that sharing an IRQ is causing a performance problem you can try getting the cards to take separate IRQs by one of the following methods.

Try changing the PCI slot that theCore-32 or Core2 card is in or the slot that the card sharing the IRQ is in.

Try switching the spots between the Core32 and Core2 card and the SCSI card. That may help to get Lexicon onto its own IRQ.

Check your BIOS. If you have PnP OS aware set to no, try changing it to yes and see what happens. WARNING: changing settings in your BIOS can effect the operation of your computer. It is advisable to note your settings before changing them.

Although some customers have reported success using Core2 in an Athlon processor equipped computer, others have reported crashing and freezing with the Athlon processor. Lexicon has not had success in our tests with the Athlon processor and currently we do not recommend it's use with the Core 2. Lexicon has been made aware of problems with the Athlon processor and the Motorola 56000 chip used in Lexicon Studio products. We are monitoring this problem in hopes that AMD and Motorola will arrive at a future solution. Until further notice, the Athlon processor is not qualified or supported by Lexicon for it's Lexicon Studio products.

Lexicon's recommendations for computer systems for the Core2 & Core32 are as follows:

Pentium Processor, PII or PIII recommended.

Intel SE440BX motherboard and chipset, without onboard soundcard.

AGP Video card.

64 MB RAM (this is minimum, 128 is better).

A/V compatible IDE hard drive, dedicated to audio (in addition to system drive).

Windows 95 or 98 operating system.

Parallel Port interfaceable MIDI controller (as opposed to USB interfaceable)

SoundBlaster also make a number of compatible MIDI interfaces.

Many people have had difficulty with the U2W SCSI drives causing clicking in the audio. We suggest using comparable IDE drives - they don't seem to be as problematic and have similar performance.

The product has been successfully tested under an AMD® K6 2 processor system. However, some software programs do not have these processors on their qualified systems lists. We recommend systems with Intel Pentium® processors.

Lexicon recommends the Intel SE 440BX motherboard and chipset, without the onboard sound card. We also recommend and support Pentium processors, PII and PIII preferred.

A Universal Serial Bus is a simple and flexible way to connect external devices to your desktop or notebook PC. A single connector type for many uses, including devices that in the past used serial ports, parallel ports, the keyboard port, the mouse port, and game ports as well as new kinds of devices. All kinds of devices can be hooked to the PC through the same connector simultaneously - modems, printers, mice, joysticks, scanners, keyboards, etc. A USB uses less real estate than existing ports (particularly important for laptops) Reduces requirements for PCI slots, allowing footprint reduction for desktop systems.

No - the card cannot be used in a 64-bit 66MHz PCI slot. We only work with the 32 bit slots.

At this time, Lexicon has no plans to develop a reverb based plug-in for VST, Direct X, Etc.

For a 1 minute mono recording you will need approximately 8MB. Double this for 1 minute of stereo. Don't forget to multiply Megabytes by the number of tracks you will be recording (e.g. 4 tracks of mono you will need 4 x 8 = 32MB per min.).

THE MATH:

48,000 samples per sec

x 24 bits

---------------------------

1,152,000 bits per sec.

1,152,000 ? 8 (bits per byte) = 144,000 bytes per sec.
144,000 ? 1024 (bytes per kilobyte) = 140.625 Kilobytes per sec
140.625 ? 1024 (kilobytes per megabyte) = .137329 Megabytes per sec
.137329 x 60 (sec per min) = 8.2397 Megabytes per min (mono)

Obviously, if you want to figure this out for different bit rates/sampling rates change the numbers and perform the same calculations as above.

To disable USB, Right click on My Computer/Properties/Device manager. Click the plus next to Universal serial bus controller. Double click on the first item under Universal serial bus controller (It should be USB root Hub). In the properties menu put a check in disable in this hardware profile. Do the same for the other entries under Universal serial bus controller.

Please make sure that before you disable the USB port that the Mouse and Keyboard are not USB. Also if you have a USB printer remember to re-enable the USB port when you want to use it.

Lexicon has no plans for support of Mac OS X.

No. Lexicon does not support MAC Clones.

You would most likely need a separate PCI slot, not shared. There may be a way to force a change through the BIOS, but you would have to contact the PC manufacturer for ideas on that.

No, SCSI signals travel on a parallel bus. You can hook up more than one SCSI device by daisy-chaining them together. Usually SCSI devices will include two SCSI connectors to allow the device to be daisy-chained.

For a system to benefit from EDO RAM, it must be capable of addressing EDO RAM, and all memory installed must be EDO. Some systems will allow you to mix FPM and EDO RAM, but the EDO modules will perform as if they were FPM. Check with your PC manufacturer.

(All DRAM addresses data the way a spreadsheet does, by organizing data into rows and columns. When Fast-page Mode (FPM) DRAM accesses data it must find the row and column, and then read the data before moving on to find the row and column for the next piece of data. EDO RAM speeds this process up by allowing the steps to overlap. EDO RAM still must find the row and column of the data before it can read it, but now it can find the row and column for the next address, while it reads the data at the first address (and so on). This speeds up data transfer rates, since EDO RAM can access data continuously without waiting for addresses to be located.)

There hasn't been any known or reported problems with Core 2 on IRQ #2. Usually when it is installed it doesn't get put on IRQ 2. The common IRQs we have seen it go to are 9,10,11 and sometimes 3, but thist all depends on how many devices are in the PC and what resources are left. It should be all right if you can get it so it is only card with the holder for PCI steering.

Lexicon has not tested the Studio products on this platform and we do not support the platform. We have had one report from a customer UNSUCCESSFULLY attempting to run Lexicon Studio Core2 the Soyo board with the ETEQ chipset.

Identify the BIOS type your computer is currently using by observing the first few lines on the display after a cold start. For example: Awards BIOS 4.51 will be displayed at the top left of the screen. A BIOS ID string will be displayed on the lower lefthand corner of the screen. Somewhere in this string should be a group of numbers that reflect the date (-120992) Note this date and number. Pressing the Pause/Break button will halt the display so that the BIOS type and version can be noted.

Another method for viewing the date of your motherboard BIOS:

From the START menu select RUN

Type DEBUG

At the cursor (-) type D FFFF:5 L 8 and press ENTER

Note: The BIOS type and date is also displayed when the computer is restarted. This string may disappear too quickly for you to read it. Try holding down a key while powering up your computer. This will cause a keyboard error message to be displayed and until you release the key the BIOS identifier string will remain displayed.

Problems that we have encountered with customers using the AMDs are popping and clicking in the audio. The only way to resolve these cases was by the customer switching over to an Intel Pentium processor. Your system may work, but we can't garauntee that you won't experience the same and we do not recommend non-Intel/Pentium processors.

In one case, Dell's technical support suggested an older driver for this Modem and when installed, the problem was resolved. Dell suggests customers with this problem download and install this file at:

www.dell.com/support/filelibrary

Get it from search by file name: pcimdm9x.exe

We recommend that you contact Dell for further instructions and assistance.

Try switching the spots between the Core2 card and the SCSI card? That may help to get Lexicon onto its own IRQ.

Reason:

The Event Gina® card uses the same VENDOR ID number as Lexicon Studio. This VEN ID number is entered in the Windows95® Registry when Gina® is installed. The entry remains in the Windows95® registry after the Gina® card is removed. When the Core32 is installed, the registry sees it as a previously installed Gina® card and attempts to configure it as such.

WARNING - If you are not familiar with accessing and making changes to the Registry settings, please contact Lexicon Customer Service Technical Support or your computer manufacturer or retailer.

WARNING

Before modifying any of the system files or Registry entries a backup copy should be made in the event that irreversable damage is done to one of these files.

The CONFIG.SYS, AUTOEXEC.BAT,\WINDOWS\WIN.INI and WINDOWS\SYSTEM.INI. should be copied and renamed before attempting to modify them. This can be done from Windows95 Explorer.

Method #1 - Press the start button, press run, type REGEDIT, Select Export from the Registry menu, Choose a file name. If necessary the Registry may be Imported by selecting Import from the Registry menu.

Method #2 - There is a Registry backup and restore utility in the Other\Misc\Cfgback folder on the Windows 95 CD-ROM (CFGBACK.EXE and CFGBACK.HLP) it is very easy to use. If this is not available do the following:

Method #3 - Before modifying any of the entries in REGEDIT, copy the SYSTEM.DAT file, this is the most current version of the regisrty, and rename it SYSTEM.DA1. Also copy and rename the SYSTEM.DA0 file, this is the most resent backup of the SYSTEM.DAT file. In the event that both of these are damaged during your troubleshooting session, you can use these new backup files to restore the registry to it's previous state. On a system that has multiple users, a copy of the USER.DAT and USER.DA0 should also be made. These files are hidden and must have their attributes changed before they can be copied. From DOS type - attrib -s -h -r C:\Windows\SYSTEM.DA? enter, then type attrib -s -h -r C:\Windows\USER.DA?. These files are now visible in Windows explorer or MSDOS mode. After troubleshooting session, these files attributes should be reset by using the command attrib +s +h +r.

Windows Explorer may show these files even after you have changed the attributes back. The reason is not known.

Highlight the VEN_1057&DEV_1801 entry(s) and delete them.

Close regedit and reboot the computer.

Windows95® will automatically reconfigure the card and the registry entry upon reboot.

If there is a GINA® card installed it too will reconfigure.

The Core 32 is a full size spec PCI card and may not fit in the HP Pavilion. The Core2 system is a half lenth PCI card that may fit your computer. Here is a link to our web page and the description of the product: http://www.lexicon.com/Core2/index.html

(according to Manny). Most of these machines ship with a US Robotics Voice Modem in them. Manny says that the voice modem needs to be above the Core card in the computer (eg; if it's a tower and the top slot is slot 1, the modem should be in 1 and the core card in 2).

If you are using the Core2 system, make sure that you are using the latest software version. The first release of the Core2 software exhibited this problem but it has been fixed in subsequent releases. You can find the latest software version at: http://www.lexicon.com/downloads/core2_current_studio_download.htm

Download and install the latest software version.

If you are using the Core32 system, the solution is to run a patch that is available on the lexicon website at this URL: http://www.lexicon.com/downloads/studio_download.htm

Select the Core32 section, then select Core32 PC V4.20 Patch #3.

Download the file named: C32V420P3.exe.

Once you have downloaded this file to your computer, double click on it to let it run, then restart your computer.

This is normal. An IRQ Holder for PCI Steering may be displayed when you view the System Devices branch of Device Manager. An IRQ Holder for PCI Steering indicates that an IRQ has been programmed to PCI mode and is unavailable for ISA devices, even if no PCI devices are currently using the IRQ.

After removing the file AWEMON32.DLL from the WIndows®/System folder both programs booted normally. The computer that this problem was reported on was a GATEWAY 300® with an Ensoniq® sound card and Lexicon Studio.

Here are our experiences with configuring the DELL Dimension T450 to work with Lexicon Studio. One general statement needs to be made here. This problem appears to be due to a wave Voice/Modem pci card. The symptom is MEMORY PARITY ERROR blue screen is displayed at boot time.

If there is no modem pci card, then the problem is not the same (at least as we understand it currently)

The T450 has 1 shared isa/pci slot and 4 fully masterable pci slots

To fix the problem:

Note: Please follow the manufacturers instructions for opening and closing your computer and removal and addition of cards.

1. Turn off power and remove the modem card. Place the Core card in the first non shareable slot (slot #2)
2. Startup the computer and install the Core drivers and reboot the computer.
3. Make sure the Lexicon card is not sharing an IRQ with the USB controller (usually IRQ 9). This may force you to use Patch 4 (Contact Lexicon Customer Service) and let the OS do the pNp.
4. Power down the computer and reinstall the modem card on the next available slot. Restart and let the system install the drivers for the card. This may take 2 reboots to finish since it's a multifunction card. The card that we encountered is a 3Comm card but it is seen as a US Robotics device (the vendor id used in their pci interface is from U.S. Robotics). When it asks you for the Wave driver for the card, pick select from the list and select the 3COMM soudwave driver.

The problem seems to be caused by the 3Comm Voice/Modem card wanting to be installed after the Lexicon Card. By removing the card first and installing the Core card we force the system into that sequence of installation. Simply removing the device from the System Manager then powering down , installing the Core card and restarting may still install the modem card first making it fail. Reinstalling it in the same slot it was installed in the first place may not reassign resources as it normally would. It is not slot dependent from what we can tell , but because of the way pNp assigns resources we must do the moves described above.

Please note - this scenario was encountered and tested with a Lexicon Studio Core2 system but could occur with a Core32 system as well.

Right click Desktop, select Properties. The Display Properties window will open. Select the Settings tab. Click on the Powerdesk button. Uncheck Use Bus Mastering and Use automatic PCI Bus retries.

Go into the Device Manager, open the System devices catagory, highlight the PCI bus entry and click the properties button. Under the IRQ steering tab make sure IRQ Steering is unchecked.

Notes:

Windows? versions 4.00.950 and 4.00.950A will not exibit this problem. These versions do not have an IRQ steering tab or the option to enable Windows? to steer IRQs. IRQ steering is done by the BIOS.

Windows? versions 4.00.950B and 4.00.950C will exibit this problem only if the option to enable IRQ Steering is enabled. Windows?, by default, does not have this option enabled.

(Refer to Article number Q182604 in the Microsoft knowledgebase for a complete description of PCI bus IRQ steering.)

WARNING - If you are not familiar with accessing and making changes to the default BIOS settings, please contact Lexicon Customer Service Technical Support or your computer manufacturer or retailer.

Changing settings in your BIOS can effect your computer's operation. It is advisable to note your settings before changing any, in the event you wish to change them back.

Warning: Please follow the manufacturers instructions for opening and closing your computer and removal and addition of cards.

Remove Lexicon Studio from the device manager. Shut down computer. Turn off power and move the Core card to slot 1. Try running the Compaq setup utility and see if it will allow you to specify an unused IRQ. A message saying that there may be other devices dependant on this IRQ may be displayed and the IRQ may carry the other device with it. The embedded devices (network and Sound) can be disabled to free an IRQ.

----------------------------------------------

Getting into the setup utility -

1. <F10>
2. >Computer Setup
3. >Add in Devices
4. >PCi Boards ---> Enable Bus mastering
5. Select Multimedia Controllers (this is the lexicon Studio card)
6. hit View
7. From pull down menu (Default Config) select Config Group 1
8. Select IRQ
9. hit Change
10. Pick a free IRQ
11. exit.

If Lexicon is not assigned an IRQ when it is installed into a Compaq Presario or if it is assigned an IRQ but is sharing with other devices, the manufacturer does not provide a way to disable Plug and Play in the BIOS or to manually change IRQ settings on this machine. There seems to be no solution to the problem.

(This is from the Steinberg Cubase online help files)

High Speed SCSI Cards:

High performance SCSI cards like Adaptec AHAA-2940UW or other Ultra-Wide SCSI host adapters can block the PCI bus because of the high data rate, which may cause crackling/clicks. This usually occurs with bus master audio cards (eg. Lexicon Studio).

If you experience crackling/clicks while using a high performance SCSI card, try reducing the maximal transfer rate of the SCSI bus to 10 MB/s. The 10 MB/s setting is still enough for up to 32 simultaneous audio tracks. Pl ease refer to the manual that came with the SCSI card for information on how to change this setting.

In addition, if the computer contains a PCI bridge it might help to put the SCSI and audio card on separate PCI segments. For example; a computer with 6 slots might be implemented as two PCI segments with 3 slots each. If a board has got more than 5 PCI slots it will definitely have a PCI bridge. The board's manual should explain which slots are on the same segment.

The best and safest way to change IRQ settings is by physically moving the card to another PCI slot, this will change the IRQ. The only other way you may be able to change this is through the BIOS, and the manufacturer of the PC would have to advise you on this one.

WARNING - If you are not familiar with accessing and making changes to the default BIOS settings, please contact Lexicon Customer Service Technical Support or your computer manufacturer or retailer.

Changing settings in your BIOS can effect your computer's operation. It is advisable to note your settings before changing any, in the event you wish to change them back.

SCSI vs.Ultra IDE

Both SCSI and Ultra IDE offer distinct advantages:

SCSI:

Benefits - fast performance, removable media, lots of choices of high performance drives

Liabilities - use of PCI card to interface to the computer increases PCI bus traffic.

IDE: Supports 2 disk drives

ATA-2: Supports four drives

Benefits - drives approach SCSI performance, inexpensive, using the IDE bus decreases activity on the PCI bus.

Liabilities - the IDE bus is slower (in most cases this is not the limiting factor) fewer model choices, no removable media. IDE allows only one device to be active on a cable at one time.

Some recommendations:

PI 200, use Ultra IDE. Less stress on the PCI bus for slower computer.

PII 233,266,300, onboard SCSI is ideal. Ultra IDE or PCI SCSI will perform well.

When using an ASIO application (such as Cubase), the available sources and destinations of Punch and Reverb are those which are enabled (active) in Cubase. If, for example, you wish to route the PC-90 from the 10T A/D 1&2 to the 10T D/A 1&2 you must activate the corresponding Input and Output bus in Cubase. The Lexicon control panel must be exited, then re-launched each time a change is made to Cubase's active streams list.

When using the Wave drivers, if the Monitor button is turned on, all channels will be available for selection in the Punch and Reverb source/destination lists. When the Wave audio application is in play, only the channels that it is using will be available to Punch and Reverb routing. The same applies if the audio application has been configured so that it keeps its audio channels open even when it is in stop mode (see the specific application's User Guide for details on how to set this up). When there is no audio application running, or the application is in stop mode and has not been configured to keep the audio channels open, all channels will be available to Punch and Reverb routing. (Also refer to Addendum #6)

If you are using the Wave drivers and make any changes to the Routing Tab in the Lexicon control panel, you MUST restart Windows in order to have these changes take effect. If the ASIO drivers are being used, it is not necessary to restart Windows. Simply quit then re-launch the audio application in order for the routing changes to take effect. If you are using Cubase, for example, and see that some of the Input or Output buses have a blank label, this is an indication that the application must be restarted. If you are using Cubase and have launched the Lexicon control panel from the Windows Taskbar, Cubase must be quit before changes can be made to the Routing tab.

Note: At least one Input pair and one Output pair must be enabled in order to launch Cubase. If no streams are active, an error message will come up saying that the ASIO Lexicon Studio v4.2 driver could not be loaded. If this occurs, quit Cubase, launch the LexPanel from the Windows Taskbar, turn on one or more I/O streams, then re-launch Cubase.

Changes to the clock source in the Lexicon Control panel are not reliably recalled.

From the Installation Instructions:
--------------------------------------

The ASIO installation instructions fail to tell you to OK a second "copying files" window.

From the Getting Started section of 12T System user Guide:
--------------------------------------

Pg.1 - A read-me file is not included with release V3.02. The latest information is available in the Studio manual Addendum.pdf file installed with the PC90 software in your IDS folder.

Pg.1 - The system requirements as referenced to in the Getting Started Section section has changed from 166MHz to 200MHz.

Pg.2 - The Versions of Windows that Lexicon Studio is compatible with has changed from Windows 95 A and up to all versions of Windows including Windows 95 V.0.

Software Installation section of 12T System user Guide:

This is made possible by a unique combination of on-board DSP, RAM and proprietary LPC processing. Our Core-32 card delivers the power to make your system rock."

On board DSP- We are using the latest, fastest 56301 DSP. This chip has built in PCI features that we are using as well.

On board RAM- This will be used in the future for when we implement our own disk management.

On board mixing - By mixing audio directly on the Core32 during punch record, we do away with the latency problems of mixing on the computer's CPU.

Bus Master - The biggest advantage we have is that we are a PCI bus master. Bus-mastering support allows the Core32 to take over the system bus, and move data into or out of system memory directly. All the CPU has to do is program the operation, and the Core32 takes it from there.

LPC processing - This is a marketing name given to the above features and our design.

Aservice is used for getting responses back from the card and for popping up notifications such as clock source and Sample Rates.

It generally means that Logic is not able to initialize the audio hardware. This can occur if the audio driver has crashed, or is being used by another program.

This is the response that Emagic has been giving users in reaction to people asking this question.

"There can be many things. This can simply mean that the number of audio tracks and effects that you are playing requires more processing power than your CPU offers, or that the number of tracks has exceeded the ability of your hard drive/controller to deliver the data quickly enough. Any system will eventually give this error, if you add enough tracks and effects. Sometimes disk fragmentation, graphics card problems or other hardware conflicts can cause this to happen with a DSP allocation that the system would normally be able to handle."

The following are the latest specifications for the Lexicon Studio interfaces.

This was a problem in early 4.0 versions. AFAIK, it is fixed in 4.04.

It is possible to get Cool Edit to record at 48 kHz. Follow these steps:

1. In Cool Edit, go to the File menu and select New.
2. In the "New Waveform" or "New Multitrack Session" pop up window, select 4800 as the Sample Rate.
3. Press OK
4. Now, if you look in the lower right hand corner of the Cool Edit window, you will see that the file properties read 4800 as the sample rate.

No. According to Emagic, you need DirectX capable sound card to use the Waveplayer. If you have a Soundblaster compatible sound card in your computer, use it to access Waveplayer.

The LDI 10T has differential outputs with <600ohms in each leg. If it is loaded with a balanced 600ohm load, the output will be significantly down from the unloaded level. Nominal balanced output : +26dBu/+17dBm.

No. The ADAT Toslink port can receive and send 20bit audio data.

We are currently investigating incompatibilities with Cakewalk Pro Audio 9. We are working with Cakewalk on these issues but do not have an estimate on when any fixes will be available.

We do work with Cakewalk 9 when Wavepipe acceleration is disabled! See page# 2325

The initial release will work with Steinberg VST PC. Steinberg VST is not included with Lexicon Studio.

Yes. The 03D and O2R have an optional ADAT interface so you can transfer 8 channels digitally between the Yamaha and the Lexicon card. Just be sure to use the correct clock source settings on both the Yamaha console and the Lexicon Control Panel. Remember that one of them must be the master and the other must be the slave.

The Logic Audio Device Setup utility runs when you install Logic, scans the system, and creates "virtual' drivers for Logic to use, based on the hardware it detects. if you add audio hardware to the system after installing Logic, you can run LADS again, and it will re scan the system, adding new "virtual" drivers for Logic to use.

Both the Core 2 and the Core 32 have been out of production and development for quite some time now, although tech support for users is still available. Lexicon has no announced plans for any futher products of this kind.

Because Lexicon Studio is a bus master it does not use system DMA channels.

Though you often see sampling rate and bit length specifications at the same time they are not tied to each other. The Lexicon Studio offers 24 bit conversion and throughput at 44.1 or 48 kHz.

Though you often see sampling rate and bit length specifications at the same time they are not tied to each other. The Lexicon Studio offers 24 bit conversion and throughput at 44.1 or 48 kHz.

VST Audio to ADAT Tape

CONNECTIONS:
Connect the 12T OPTICAL OUTPUT to the ADAT DIGITAL INPUT.
The ADAT will need to be set for the digital input that is the same sample rate as the song in VST and should be referencing the digital word clock. (DIG)
The ADAT inputs should be set to DIGITAL.

CUBASE SETTINGS:
From the VST Master window enable BUS 3, 4, 5 and 6

Verify that the output of BUS 3 is TOSLINK 1, BUS 4 - TOSLINK 3, BUS 5 - TOSLINK 5 and BUS 6 - TOSLINK 7.

In the VST Monitor window assign the channels outputs to BUS 3 - BUS 6 respectively

If you are using the Core32 system, launch the Lexicon Control Panel and go to the Control I/O tab (the LDI 12T tab if you are using software version 4.2) set the Output to S/PDIF RCA / ADAT OPTICAL

Set the Audio Clock Source in the Audio System Setup page to Internal. The Sample Rate should remain at the setting that the Song was created in.

Press RECORD/PLAY on the ADAT device and PLAY on the VST transport bar to start recording.

ADAT CONNECTIONS:
Connect the ADAT DIGITAL OUT to the OPTICAL IN of the 12T or Core2
Verify that your ADAT's clock is set to INTERNAL.
The ADAT's sample rate is automatically determined by the sample rate that the tape was formatted to.
From VST - Enable the Toslink inputs and assign them to input channels from the Monitor window.

CUBASE SETTINGS:
From the Options menu in VST select Multirecord and verify that there is a check mark next to Active.

In the Arrange window, enable the channels for record.

From the Audio System Setup page set the Sample rate to the sample rate that the ADAT is set to.
In this same page set the Audio Clock Source to ADAT Data (this setting will read LDI 12T ADAT Data if you are using the Core32 system)

RECORDING:
Start recording in VST, then press PLAY on the ADAT device.

To stop recording press STOP on both the ADAT device and on the VST transport bar.

Important: Playback of the recorded tracks can be done while still referencing ADATDATA as the Audio Clock Source. If you are going to disconnect the optical cable from the Core2 or 12T or if you are going to power off the ADAT device set the Audio Clock Source in VST to Internal.

Connect a light pipe from the Yamaha 01V Toslink out to the optical Toslink input on the Lexicon system.

(Note: If you are using a Core32 system, launch the Lexicon Control Panel and go to the Control I/O tab or LDI 12T tab and set the Output to S/PDIF RCA / ADAT Optical. Set the Input to S/PDIF RCA. Close the Lexicon Control Panel)

In Cubase's Audio menu, select Inputs. Activate the ADAT Toslink inputs and note their corresponding VST labels.
From the Arrange window or the VST mixer assign the appropriate inputs (the VST labels that you noted in the previous step) to the tracks or channels.
If Cubase is in Tape type monitoring, click on the button at the top of each channel to put it in Input Enable mode. You should have signal passing now.

For latency free monitoring Enable Global Disable type monitoring in the Audio System Setup page and from the Lexicon Control panel select the Punch tab, enable Punch and set the Sources to Toslink (or ADAT) 1-8 and destinations to the output you are using to monitor. This type of monitoring takes all of the ADAT inputs, sums them to mono and sends them to the output specified by the destination setting.

To disable AutoPlay or change playback device:

1. Double-click the My Computer icon.
2. On the View menu, click Options, and then click the File Types tab.
3. Click the AudioCD type, and then click Edit.
4. In the Actions list, click Play, and then click Set Default.

Tip:
To temporarily disable AutoPlay, press the SHIFT key when inserting an audio CD.
To reenable AutoPlay, repeat steps 1-4.

First, you must make sure that you have installed V3.10 or later of the lexicon Studio Core32 drivers. Any version of the Core2 drivers will be able to play Windows sounds. If you see a small Lexicon Studio icon next to your clock on the task bar you have the correct version installed.

Note: Playing Windows sounds through the Lexicon card may interrupt audio playback or record in audio applications. It is recommended, if you have another sound card in your computer, that you play Windows sounds through it instead of through the Lexicon sound card.

Go to the Windows Multimedia Control panel. Make sure that you select the desired Lexicon output as your preferred Playback device. Put a check in the box that says, "Use preferred devices only" Go to the Windows Sounds control panel and select a sound scheme.

Only the 12T has been discontinued. We are continuing to develop software for the 10T.

The Lexicon Studio line does not run under Windows NT, and there are no plans to develop drivers for this at this time. The Core 2 , right now is PC only and runs on Windows 95 or 98. MAC drivers will be available, but there is no exact release date for them.

FCC classification is not based on recording quality. Whether equipment is Class A or Class B is based solely on where it is meant to be used. Once that is determined, the equipment must meet specific FCC requirements related to possible interference with radios or televisions. The requirements for FCC Class B equipment are more stringent than for Class A equipment, so it is better to have Class B equipment, which is meant to be used everywhere.

Yes.

Yes.
We wrote an ASIO driver for our hardware to work with Steinberg's VST.

We do implement full re-synchronization of word clock but the Time Code re-synchronization is controlled by the individual audio application. Often, in an application's preferences you can select whether you would like it to perform a full resync or merely reposition the playback cursor.

The Lexicon Studio systems are compatible on Windows 95 and 98 only. Lexicon has no plans for support of Windows® 2000, Windows® ME or Windows® NT.

No, having a second sound card in your system would not affect the audio performance of the Core2. The only thing that could happen would be that your system would not be able to assign the new sound card an IRQ without it sharing with the Lexicon Studio system. This could happen if your system does not have any free IRQ's after installing the Lexicon Studio system. It is also possible that it would not be a problem, or that the problem could be resolved by moving cards around in your system.

Lexicon Studio does not need to have DirectX installed. The PC90 and MP100 are hardware based effect plugins.

The Lexicon Studio hardware has no MIDI connectors on it.

DirectX will accept our driver in Wave mode - it will simulate DirectX by means of our Wave driver.

The Lexicon Studio hardware has no MIDI connectors on it. A separate MIDI interface is required.

You can have a Core32 OR a Core2 in your system at a time, but not both together.

AES formats AES/EBU and S/PDIF are very closely related, although there are very slight differences in the digital information sent. In many cases it is possible to run one into the other with good results - it really depends on the two devices you are connecting. Some devices actually allow you to switch which format is carried on their digital connections, which solves the problem.

The two formats are a bit different electrically though. S/PDIF is high impedence and unbalanced, while AES is a low impedence, balanced format. This means that AES will survive long runs much better (up to 100 meters) and will have less problems with RF interference. The levels the two operate at are also different, which might cause distortion problems when running one type into the other. Try using a balanced to unbalanced adapter described below.

XLR female:
	P1---------P3 and tie to ground
	P2---------200ohm resistor---------Male RCA tip
			|___ 200ohm resistor -------- tie to ground
RCA male: tie shield to ground

Your best bet is to run AES into AES, and S/PDIF into S/PDIF. If you must interconnect them, use an appropriate format converter. But in a pinch, you can try running one into the other for a quick transfer.

Disclaimer: The S/PDIF consumer digital input was not designed to accept input from an AES source. The above suggestions may not yield reliable results and should not be used for critical digital audio transfers. For a long term solution to this problem consider upgrading your digital audio interface or use a format converter.

We do not have plans for NT.

We do not have plans for Beos right now. We are still currently working on the MAC drivers that will make the Blue and White G3s compatible, but there is no exact date of when they will be available. When they are available it will be posted on http://www.lexicon.com.

There are no audio input level meters on the LDI12T or LDI10T. Input level metering must be done with the audio application.

The Punch feature on the Lexicon Control Panel, allows you to monitor your signal witout latency (with no delay). This will mean, however, that you will not hear any input processing performed by Steinberg, i.e. host based compression, delay, chorusing etc..... these would have to be done after recording.

We have no immediate plans to implement Apple Sound Manager drivers for the Lexicon Studio system. Please check our website (www.lexicon.com) for updated information.

Most of the Lexicon dealers that sell Steinberg and Sonic Foundry products will carry it.

This selection in the Core32 control panel applies de-emphasis to the analog outputs. Audio data recorded with emphasis has a high frequency boost. The intention was to improve noise performance. It is not a method widely used today but may be needed if the audio data has been recorded with another interface that applied pre-emphasis to the analog inputs.

Minimum System Requirements:

Macintosh:
Core 32: 200 MHz Power PC (Power PC G3 processor highly recommended)
64 MB RAM (this is minimum, 128 MB will yield better performance)
Audio - capable disk drive
Mac OS 7.6.1 through 9

Core 2 Blue and White G3 or G4
64 MB RAM (this is minimum, 128 MB will yield better performance)
Audio - capable disk drive
Mac OS 8.6 through 9
ASIO compatible applications only

PC:
Core 2 and Core 32:
Pentium processor, PII or PIII supported
200 MHz minimum processor speed ( this is minimum, a faster processor will yield better performance)
Intel SE 440BX motherboard and chipset, without onboard soundcard - recommended
AGP Video card
64 MB RAM ( this is minimum, 128 MB will yield better performance)
A/V compatible IDE drive, dedicated to audio (in addition to system drive)
Windows 95 or 98 OS
Parallel port interfaceable MIDI controller (USB interface not supported; Soundblaster also makes a number of compatible PCI bus MIDI interfaces)

You can only connect one LDI 12T to a Core 32 card and currently this is the only ADAT option for the Lexicon Studio system. You can connect up to 3 LDI 10Ts which are the 8 analog channels I/O, giving you 24 analog and your 8 ADATs.

We do not have any scheduled plans to develop drivers for BeOS.

You should not hear distortion when using the Punch feature. If you do hear distortion try bringing the Mix Level down a bit. Punch sums all selected inputs and creates a mono mix which it sends to all selected outputs. If you have several inputs selected it can overload. Bringing the Mix Level down should solve that problem.

There are no current plans as of now to create drivers for Lexicon Studio on the NT platform, we do however receive many requests for this and the quantity of these requests are noted. Please check into our website at http://www.lexicon.com from time to time to see if anything changes!

When playing files from a SCSI drive that is connect to a SCSI adapter that utilizes a DMA channel (such as most Adaptec adapters) you may experience a warbling effect in the sound playback. This can occur if your sound card uses DMA and its DMA channel is set to a higher number than your SCSI adapter.

To fix this problem, set the DMA channel used by your sound card is a lower number than that used by your SCSI adapter. So, if your SCSI adapter is set to DMA channel 5 and your sound card is set to DMA channel 7, try reconfiguring them so the sound card uses DMA channel 5 and your SCSI adapter uses DMA channel 7.

This seems like odd behaviour! Here are a few things to check:

1. In Acid's Options menu select Preferences. Go to the Sync tab. Is there a check mark next to "Synchronize audio playback devices to opened sample rate"? If there isn't, you should try it with this feature selected.
2. Are you making tempo changes in the song that is experiencing this problem? If you are, would the problem occur if there were no tempo changes being made?
3. What is the clock source set to in the Lexicon Control Panel? If you are playing back from disk or using an analog input it should be set to internal.

Please let us know if you continue to have problems.

Try muting the first 8 tracks when transferring your second 8 tracks to see if that addresses the popping. The first 8 tracks can be un-muted once the second pass has been completed.

Selecting Passive Update for Video and Time Display from the Options menu, will lower the priority of the repainting for these displays during playback. If your computer is relatively slow and you are experiencing gapping during playback, or the machine just seems to be bogging down during playback, try turning on Passive Update. This will force the repaints for the Video and Time Display to only update if there is time to do so. In most cases you won't even be able to tell if it is missing some updates, so turning these options on can decrease the amount of overhead during playback with little inconvenience.

Note: You can only access these parameters when an audio file is open.

The Play and Record Meters in Sound Forge take a small amount of processing overhead during playback and record. If you are experiencing gapping during playback and you have the Play Meters showing, try turning off the Play Meters by selecting the Play Meters option in the View menu. If you are experiencing gapping during record and you have the Monitor option enabled in the Record dialog, try turning off the Record Meters by un-checking the Monitor option.

There are also some Windows settings that may affect playback in Sound Forge:

Choosing system configuration settings other than the default Windows 95 settings can result in reduced performance from Sound Forge, as well as Windows 95. To check these settings go to System under Control Panel and click the Performance tab. File System and Virtual Memory should both be set to 32-bit. In the advanced settings area of the window, click on File System. In the File System Properties dialog, the Hard Disk tab setting for Read-ahead optimization should be set to Full and the Troubleshooting tab should have all of the options unchecked.

Now, click on Graphics in the Advanced Graphics Settings dialog. In most cases this setting should be set to Full. If you are experiencing unexplained glitching in your audio playback, try different settings. However, if changing these settings doesn't clear up the problem, change them back. Finally, click on the Virtual Memory button under the Advanced settings of the Performance page. In most cases, you should choose to let Windows 95 handle your virtual memory.

1. Verify Word Clock source in the Audio System Setup page in VST is set correctly.
2. Turn Read Ahead optimization to None in the Windows® File system properties control panel
3. From the Troubleshooting tab in the Windows® File System properties select Disable write-behind caching for all drives.
4. Try lowering the Memory per Channel and the Disk Block Buffer Size in the Audio performance section of the Audio System Setup page in VST.
5. Make sure the Core32/Core2 card is not sharing an IRQ with any other device (to check this go to the Windows® System Control Panel, go into the Device Manager and double click on Computer. If the card is sharing an IRQ, try moving the card to a different PCI slot or try disabling the device that it is sharing with.

V4.20 Addendum #8: Suggested

Try tweeking Playback Buffer size within the application itself, usually this will correct this problem. Try bringing them up in value and also down, it may be a matter of finding the best setting for your system.

Try disabling any programs running in the background during the driver installation. (Virus Scanning software especially)

Download and install patch C32V420p4.exe for Lexicon Studio Core32 or the latest software version (1.21 and later) for Lexicon Studio Core2.

http://www.lexicon.com/downloads/studio_download.htm

There are no midi functions on the Core2 or Core32 cards. The card is strictly audio, and you would have to use another card or midi device for any midi functions you want to acheive.

In the Emagic folder is an application called MMSetup.exe. Run this program. It brings up a list of current drivers seen by Logic Audio.

1. Count the number of Lexicon Playback drivers are currently available.
2. Highlight the first Lexicon Studio Playback driver.
3. Set the number of Playback drivers to the number of Lexicon Playback drivers (enter this number in the data entry box that appears below the list of drivers
4. Set the Channels per Driver to 2
5. Repeat steps 1 - 4 for the Recording drivers
6. Close MMSetup, choosing yes to Save changes to the Registry.
7. Restart your computer

These steps must be taken each time you make changes to the Routing tab configuration in the Lexicon Control Panel

Try muting the first 8 tracks when transferring your second 8 tracks to see if that addresses the popping. Also lower the transfer rate of the SCSI card to 10 megabytes per second.

Upgrade VST 3.553. Downloadable from Steinberg FTP site.

Make sure that you are using the most recent version of Cubase available to you. Lexicon Studio is compatible with versions later than 3.55R3. Versions earlier than this will not work correctly with Lexicon Studio.

Make sure that you are using the correct clock source in the Audio System Setup window. It should be set to Internal when using analog inputs.

This message will be displayed if no resources are assigned to the card.

If you are using the Core2 system, make sure that you are using the latest software version. The first release of the Core2 software exhibited this problem but it has been fixed in subsequent releases. You can find the latest software version at: http://www.lexicon.com/downloads/core2_current_studio_download.htm

Download and install the latest software version.

If you are using the Core32 system, the solution is to run a patch that is available on the lexicon website at this URL: http://www.lexicon.com/downloads/studio_download.htm

Select the Core32 section, then select Core32 PC V4.20 Patch #3.

Download the file named: C32V420P3.exe.

Once you have downloaded this file to your computer, double click on it to let it run, then restart your computer.

1. Make sure Lexicon is not sharing an IRQ with anything other than IRQ Holder for PCI Steering. If it is, try moving the Lexicon card to another slot. To check for IRQ sharing, go to the Start menu and select Settings, Control Panel. Double click to open the System control panel. Go to the Device Manager and double click on Computer. Look for Lexicon IDS Sound System in the list of devices. Take note of what IRQ it is on. Check to see if there is anything else using that IRQ (it is okay for it to share with IRQ Holder for PCI Steering). If Lexicon IDS Sound System is sharing, try moving the card to another PCI slot. Then check the IRQ again. If you are unable to get Lexicon onto its own IRQ, contact Lexicon Customer Service Technical Support 781-280-0300 or email: csupport@lexicon.com
2. Go to the Start Menu. Select settings, Control Panel. Double-click on MultiMedia. Go to the devices tab [Advanced if using Windows 95]. Look under audio devices. Double-click on Audio for Lexicon Studio Wave Device. Check the status. It should say drivers enabled and active. If it does not, restart the computer. Note - Check again and restart again if not enabled.
3. If you are experiencing pops, clicks, or random crashes, try turning the video acceleration on the graphics card down to none.
4. Turn Read Ahead optimization to None in the Windows(r) File system properties control panel
5. From the Troubleshooting tab in the Windows(r) File System properties select Disable write-behind caching for all drives (put a check mark beside it).
6. Use a separate drive or partition for audio. Defragment all hard drives regularly.
7. Run scan disk or other utility regularly.
8. Disable screen savers, background applications that aren't needed for audio, disable virus protection software while using an audio application (re-enable it whenever you are downloading files from the internet, receiving email, or inserting disks into your machine).

If the audio application boots and seems to function properly check the following:

1. From ASIO ctrl panel set time code source to LDI 12T LTC or disable time code reader. If this is set to LDI12T ADAT and no ADAT SYNC signal is connected and running this message will appear.
2. Set sync source to Internal

This problem appears in V3.02 only and has been fixed in V3.10

-----------------------------------------------------

If the Audio application does not boot check the following:

1. Is the card present under the Device manager? To check go to the Window's Control Panel and double click on SYSTEM. This will bring up the System Properties window. Click on the Device manager tab and find the Sound, video and game controller icon (or Multimedia). Expand the catagory and look for Lexicon IDS Sound System. Is there a yellow exclamation point next to Lexicon Studio Sound System?
2. Is an IRQ assigned? Is memory I/O assigned? Highlight the Lexicon IDS Sound System and click on the Properties button. This brings up the Lexicon IDS Sound System properties page. Click on the Resources tab. ther you will see a box called Resource Settings. Here you will see if an IRQ and Memory are assigned. Look below at the Conflicting device box, are there any conflicts listed?
3. Is the PC90 software installed correctly? Our installer copies files to the Cubase VST plugins directory. Score does not use this directory.

Uninstall the PC90 software. Under the Control Panel choose Add/Remove programs, highlight UnlexiconPC90, then click on remove. Next, reinstall the PC90 software. During the install change the default directory to:

For the Demo version: Program files\Steinberg\Cubase Score VST Demo\VSTplugins

For the Release version: Program files\Steinberg\Cubase Score VST\VSTplugins

Check the Steinberg directory to see if there is more than one version of Cubase installed on the computer; (C:\Program Files\Steinberg\). For example, there may be a Cubase VST and a Cubase Audio VST. Check the vstplugins folder of each version of Cubase found (programs/steinberg/cubase .../vstplugins). You may find that the only files in one of the vstplugins folder are the pc90machine1.dll and pc90machine2 .dll. The other vstplugins folder will probably have the Steinberg plugins in it. Uninstall the PC90 software and run the installer again. Make sure you read the directory path Warning carefully.

At the start of the installation process, after Windows® has identified the new hardware, Windows® searches for the drivers. In some cases Windows® will not search the correct drive. You need to manually specify the path to the A:\ drive by clicking the Browse button. Once you have done this, click Finish. All of the drivers will be copied from the A:\ drive.

In Cakewalk's Options menu select Audio. Go to the Advanced tab and de-select "Wavepipe (TM) Acceleration". Make sure there is no check mark next to this selection.

Troubleshooting: Set D/A levels to 0dB or below. Outputs may be distorting inputs to mixer or power amp.

Qualifying the This may be an interaction between the computer's PCI bus and the coredsp.pci code in version 3.02. This is more likley to happen on non-intel based computers and slower intel based computers.

1. Do the demo song or previously recorded 44.1 or 48k .wav files play back normally through Lexicon Studio?
2. Is the audio quality good when monitoring with Punch enable and Global disable? (Not monitoring through the vSt mixer)
3. Is the audio quality bad when monitoring through the vSt mixer with punch disabled and Record or Tape Type monitoring enabled?

If you have answered 'yes' to the quesions on the left, obtain new drivers for Lexicon Studio. Newer versions of the Coredsp.pci contained in drivers later than v3.02 have been optimized for slower and non-Intel based PCI chip sets.

Move card to another slot. It is possible that the card was installed in non-bus masterable slot or a bad slot.

If your Windows Font setting is set to "Large Fonts" the button appears in the wrong location. Set your Windows Font to "Small Fonts" to correct this. To do so go to your Settings tab on the Display Properties page. We are not aware of any other function of the control panel that is effected by the "Large Fonts" setting.

1. From Wavelab's Option menu select Preferences, then the Audio Card tab. Make sure the playback device is set to one of the Lexicon outputs
2. Make sure the playback resolution is set to 8, 16 or 24bit. 20 bit is not supported at this time.
3. If you have VST open and are using the ASIO drivers, Wavelab with WAVE drivers will not work. Can not load both drivers simultaneously.
4. If you are using VST with the WAVE drivers and are using WAVELAB as your preferred editor you must uncheck play Audio in background in the VST File/Preferences menu.
5. On some systems it is necessary to record a short section of audio before you can play back a file. This only needs to be done once when you first open Wavelab. The duration of the session should be fine.

Sync Reference: Sample Position - Output

Card Options:

Activated: Full-Duplex, Start Input First
De-Activated: Open all Devices before Start

Audio Buffers: 5
Buffer Size: 5512

Notes:

1. With this settings the card will perform audio recordings with 16 bit resolution in full-duplex operation, while the output will give you 8 bit resolution. For a playback with 16 bit resolution you have to de-activate the input in Cubase VST in the Audio menu's "Inputs" window.
2. If you use an AWE 64 or the WaveSynth upgrade for other Soundblaster cards you have to de-activate the Wavesynth/WG (Creative Music Synthesizer) MIDI output port in the Setup MME program which comes with Cubase VST. Also it might be necessary to disable the Creative Instrument Mapper. It is not possible with a SoundBlaster card to use the WaveSynth and audio recording capabilities simultaneously.
3. Certain combinations of System BIOS and Sound Blaster Drivers have been observed as producing a system freeze when Full Duplex mode is selected. Deselecting Full Duplex mode normally will make this problem disappear. Please contact Steinberg or Creative Labs for the best driver version for your machine.

1. Make sure the connector box is plugged in and, if it is a 12T or 10t, make sure it is turned on.
2. Make sure that the interface cable is connected to both the Core card and the connector box.
3. Set the clock source to a known good source. The outputs will mute if the selected clock source is not connected or is not valid. Internal is a good setting for test purposes.
4. Make sure the inputs are enabled - Some applications require that the cards input be turned on before it can be assigned as a record source. (example: Audio/Inputs menu in VST)

If after installing Lexicon Studio drivers and restarting your computer your computer boots with the message: 'Core32 or Core2 not installed' or 'not working properly', for Core2, go to http://www.lexicon.com/downloads/core2_current_studio_download.htm and download the latest software version. Follow the directions on the same web page for update instructions.

For Core32, go to http://www.lexicon.com/downloads/studio_download.htm and download Core32 PC V4.20 Patch: C32V420P3.exe. Double click on the file, let it run (using all of the defaults), then restart your computer.

1. Make sure Lexicon is not sharing an IRQ with anything other than IRQ Holder for PCI Steering. If it is, try moving the Lexicon card to another slot. To check for IRQ sharing, go to the Start menu and select Settings, Control Panel. Double click to open the System control panel. Go to the Device Manager and double click on Computer. Look for Lexicon IDS Sound System in the list of devices. Take note of what IRQ it is on. Check to see if there is anything else using that IRQ (it is okay for it to share with IRQ Holder for PCI Steering). If Lexicon IDS Sound System is sharing, try moving the card to another PCI slot. Then check the IRQ again. If you are unable to get Lexicon onto its own IRQ, give Lexicon Tech Support a call at 781-280-0300 or email: csupport@lexicon.com
2. Go to the Start Menu. Select settings, Control Panel. Double-click on MultiMedia. Go to the devices tab [Advanced if using Windows 95]. Look under audio devices. Double-click on Audio for Lexicon Studio Wave Device. Check the status. It should say drivers enabled and active. If it does not, restart the computer. Note - Check again and restart again if not enabled.
3. If you are experiencing pops, clicks, or random crashes, try turning the video acceleration on the graphics card down to none.
4. Turn Read Ahead optimization to None in the Windows(r) File system properties control panel
5. From the Troubleshooting tab in the Windows(r) File System properties select Disable write-behind caching for all drives (put a check mark beside it).
6. Use a separate drive for audio. (Do not partition drives for audio.) Defragment all hard drives regularly.
7. Run scan disk or other utility regularly.
8. Disable screen savers, background applications that aren't needed for audio, disable virus protection software while using an audio application (re-enable it whenever you are downloading files from the internet, receiving email, or inserting disks into your machine).

Here's how to check for IRQ sharing:

Go to the Start menu and select Settings, Control Panel. Double click to open the System control panel. Go to the Device Manager and double click on Computer. Look for Lexicon IDS Sound System in the list of devices. Take note of what IRQ it is on. Check to see if there is anything else using that IRQ (it is okay for it to share with IRQ Holder for PCI Steering).

1. Try moving the Lexicon card to a different PCI slot. Turn the computer off, put on the wrist strap that came with the Core2 to prevent static damage, take the Core2 out of the PCI slot that it is in and move it to a different slot. If you do not have any other empty PCI slots, try swapping positions with another PCI card. Make sure that you have drivers for the other PCI card handy, as they may need to be reinstalled. Once the PCI card is securely placed in the new slot, turn the computer back on. The software for the Lexicon card should automatically be found and reinstalled for the new position. Check the Device Manager again to see if the Lexicon card is still sharing an IRQ. If it is, try another PCI slot. Continue swapping cards and moving cards around until the Lexicon card does not share an IRQ
2. If you are unable to get the Lexicon card on its own IRQ by moving it to a different PCI slot, you can try disabling other devices to free up resources. If you are not using the USB port for anything, try disabling it.
3. If you are unable to disable other devices to free up resources, try removing other cards that are not vital to your system (for instance a sound blaster card or modem card).

Yes, the track total can be higher, but you can only record 8 tracks.

We strongly recommend using Logic 4.1.1 in MMIO mode only. In addition, we recommend saving a named device setup in MMIO mode, using the device setup program. This will prevent Logic from being "confused" about whether it has been started in MMIO or ASIO mode. Remember to re-boot your computer after any configuration change in MMIO.

Yes...It is possible to have one 12t and up to three LDI-10Ts connected at one time. If you want to connect more than one 10T to a Core32 card, you need the LX3 connector.
