Chapter 5: Installing Pro Tools Software 45
OMS searches for and displays any detected
MIDI devices. Some older instruments, as well as
some newer ones, may not be recognized by the
OMS auto-detection routines.
Devices not recognized by OMS appear with a
red question mark and are named based on the
interface or port to which they are connected.
These devices can be defined as necessary within
the OMS Setup application (see “Defining MIDI
Devices in OMS” on page 45).
4 Click OK to save your Studio Setup document.
Defining MIDI Devices in OMS
To define a MIDI device in OMS Setup:
1 Double-click the device’s icon in the Studio
Setup window.
2 In the MIDI Device Info dialog, select the
Manufacture and Model for the device from the
pop-up menus. If the device is not listed, leave
the Model set to “other” and enter a name for
the device.
3 Select the receiving channel for the device. If
receiving multiple channels, select the option
for “Is Multitimbral.”
4 If you will record from the device in Pro Tools,
select the option for “Is Controller.” If the de-
vice will be a source or destination for MIDI
Time Code, Beat Clock, or MMC, select the ap-
propriate option.
5 Click Ok.
Disabling SerialDMA in OMS
Pro Tools requires that you deselect the “Use
Apple Serial DMA Driver When Available” op-
tion in OMS Setup. If you do not disable this op-
tion, problems will occur with MIDI and syn-
chronization functions in Pro Tools.
To disable SerialDMA in OMS:
1 Double-click the OMS Setup application.
2 Choose Edit > Preferences.
3 Deselect “Use Apple Serial DMA Driver When
Available.” and click OK.
4 Quit OMS Setup
Machine Control and the IAC
Driver
If you are planning to use MIDI Machine Con-
trol (MMC) for Pro Tools synchronization with
other MMC-capable devices or applications, you
must rename the OMS IAC Driver and remove
the infinity symbol (“∞”) from its name. If you
do not do this, MMC will not function properly.
