Configuring Logic Audio

You'll configure Logic Audio a little differently depending on whether you're using Windows or MacOS computers, and depending on whether you're using OASYS PCI as your main audio I/O hardware, or as a synthesizer and effects processor alongside another audio I/O card.

Windows

If you will be using OASYS PCI as your main audio I/O hardware, start with Configuring MIDI, and then move on to Configuring Audio. When you've completed those steps, you're done.

If you will be using OASYS PCI as a synthesizer and effects processor in conjunction with another audio I/O card, such as the MOTU 2408, just follow the instructions under Configuring MIDI. Next, check out the information in Setting Up OASYS PCI For Use With Other Audio Cards. After that, you're done!

MacOS

If you will be using OASYS PCI as your main audio I/O hardware, start with Configuring OMS. After completing those instructions, move on to Configuring MIDI, and then to Configuring Audio. When you've completed those steps, you're done.

If you will be using OASYS PCI as a synthesizer and effects processor in conjunction with another audio I/O card, such as the MOTU 2408, start with Configuring OMS, and then move on to Configuring MIDI. Next, check out the information in Setting Up OASYS PCI For Use With Other Audio Cards. After that, you're done!

Configuring OMS (MacOS)

Install OMS (MacOS)

On MacOS computers, you will need to install OMS before using Logic with OASYS PCI. It is best to install OMS before installing OASYS PCI; this ensures that the OASYS PCI installer places all OMS-related files in the appropriate places on your disk.

For more information on installing OMS, and on setting up OASYS PCI with OMS, please see OASYS PCI and OMS.

Enable OMS in Logic (MacOS)

For use with the OASYS PCI on MacOS computers, Logic Audio should be set to use OMS as its MIDI system.See the Logic Audio manual for more information.

1. Select Options->Settings->MIDI Interface Communication.

2. Check the "Use OMS If Available" option.

Logic will now use OMS as its MIDI system.

New files will automatically include the OASYS PCI as a MIDI device. Previously created files will need to be updated. To do this:

1. Open the Environment window.

2. In the Environment window's Options menu, select Update OMS Equivalents.

The OASYS PCI will be added as a MIDI device within the environment.

Logic Audio 4.7 and later: OMS and Logic Native Drivers can run simultaneously

Version 4.7 of Logic Audio adds the ability to use OMS and Logic's native MIDI drivers at the same time. Users report success when using this feature with OASYS PCI.

To avoid MIDI errors, make sure that MIDI instruments are not duplicated between the OMS Setup and Logic's native drivers. A single MIDI device should only be in one or the other. You may need to edit your OMS Setup to delete any duplicate MIDI devices.

Also, make sure that OMS and Logic's native drivers are not both set to use the same physical MIDI interfaces. For instance, if you have a single MIDI interface, it may be used by either Logic's native drivers or via OMS, but not both at the same time.

Configuring MIDI

MacOS: Configure OMS first

On MacOS computers, make sure to follow the instructions above for configuring OMS. After completing those steps, continue as described below.

Set up MIDI patch-through

OASYS PCI can connect directly to a MIDI interface (for standalone operation), or can use a sequencer's MIDI thru function for MIDI input. When used with a sequencer, you need to disable OASYS PCI's direct connection to the MIDI interface. To do this:

1. Open the OASYS PCI Editor program.

2. In the Edit menu, select "Preferences."

The Preferences window will appear.

3. Click on the MIDI/Global tab.

The MIDI/Global preferences page will appear.

4. Turn off the checkbox labeled "Editor Responds to OMS/FreeMIDI Controllers" (MacOS) or "Editor Responds to MIDI Controllers" (Windows).

This is similar to the Local On/Off parameter found on some synthesizers. Turning it off means that the OASYS PCI will not directly receive MIDI from MIDI controllers. Instead, it will only respond to MIDI patched through from other MIDI programs.

This setting prevents various strange things from happening, including phasing, hung notes, and notes cutting off prematurely.

5. In Logic, enable MIDI patch-through.

This will patch the MIDI output of your controller through to the OASYS PCI.

Enable MIDI Clock

For use with OASYS PCI's tempo-based effects, Logic needs to send MIDI clocks to OASYS PCI. To enable this:

1. Select Options->Settings->Synchronisation Settings.

The Synchronisation Settings dialog will appear.

2. Select the MIDI tab.

The MIDI synchronisation settings will appear.

3. Select the box to the right of Transmit MIDI Clock, so that it is checked.

4. Select OASYS PCI A from the menu.

Logic will now send MIDI Clock to the OASYS PCI.

After configuring MIDI...

If you will be using OASYS PCI as your main audio I/O hardware, move on to Configuring Audio.

If you will be using OASYS PCI as a synthesizer and effects processor in conjunction with another audio I/O card, such as the MOTU 2408, check out the information in Setting Up OASYS PCI For Use With Other Audio Cards.

Configuring Audio

If you are using MacOS, skip to Select OASYS PCI as the ASIO device, below. If you are using Windows, read on for important information.

Windows: choice of ASIO or MME

Under Windows, you can use OASYS PCI as Logic's audio hardware in one of two ways: via ASIO, or via MME. With Logic Audio version 4.6 and later, we recommend using ASIO for its improved performance and lower latency. With Logic Audio versions 4.5 and earlier, we recommend using MME.

For information on setting up OASYS PCI as the ASIO device, see below; for information on using MME devices, see the Logic Audio manuals.

IMPORTANT: With OASYS PCI version 1.0 and 1.02, some users reported difficulty in selecting OASYS PCI as an ASIO device in some Windows programs, including Logic Audio and Reaktor, when Cubase VST was *not* installed on the computer. This is now fixed in OASYS PCI software version 2.0. If you have not yet upgraded to version 2.0, there is a simple workaround; see Cannot select as ASIO device in Windows 95/98/ME for more information.

Windows: When using ASIO, do not select OASYS PCI as the default Windows audio device

Even when Logic Audio is set to use only ASIO for audio, it apparently still accesses the default Windows audio device during start-up. This can cause Logic to crash, or not be able to access the card via ASIO, when OASYS PCI is selected as both the default audio device and Logic's ASIO device.

To avoid this, when using OASYS PCI with Logic via ASIO, make sure that OASYS PCI is not selected as the default Windows audio device.

Select OASYS PCI as the ASIO device (MacOS and Windows)

1. Select Audio->Audio Preferences.

The Audio Preferences dialog will appear.

2. Optional: under Global, make sure that Release Audio In Background If Stopped is not checked.

This is not completely necessary, but since you will be switching back and forth between Logic and the OASYS PCI Editor, it may be more convenient.

3. Select Audio Driver from the menu at the top of the Preferences dialog.

The Audio Driver preferences will appear.

4. Select the ASIO checkbox, so that it is checked.

5. Click the triangle to the left of the ASIO checkbox, to show the ASIO preferences.

6. In the Current Device menu, select OASYS PCI.

If OASYS PCI does not appear in the menu, see the FAQ entry Cannot select OASYS PCI in audio/MIDI program.

Also, see the FAQ entry Cannot select OASYS PCI as an ASIO device.

7. For 24-bit operation, select the 20/24 Bit Recording checkbox.

Displaying audio channel names in Logic Audio

By default, Logic Audio will show basic numerical names for the inputs and outputs of OASYS PCI. Below is a table showing how these names map onto OASYS PCI's actual I/O.

Setting the word clock source

In Logic Audio, the word clock source is set in File > Preferences > Audio Extensions.

Make sure that the program's sample rate matches the external clock source

When you record or play back audio data using external clock sources (such as the S/PDIF, ADAT, or Word Clock inputs), the sample rate is controlled entirely by the external source, and not by the digital audio program's sample rate parameter. Because of this, you must make sure that the external clock source is actually set to the same sample rate as the digital audio program. If the two are different, it can result in audio playing back faster or slower than expected.
