appendix c
Configuring OMS (Mac OS 9 Only)
Pro Tools requires Open Music System (OMS),
which is included on the Pro Tools Installer CD.
OMS has the following capabilities:
• Keeps track of which MIDI devices you are us-
ing, how they are connected, and which
patches they are using
• Enables MIDI hardware to communicate with
your music applications
• Provides timing services and inter-application
communication
OMS stores a description of your MIDI studio in
Studio Setup documents, which are edited in the
OMS Setup application. Once OMS is configured,
your music applications know which MIDI de-
vices you are using by referencing the current
Studio Setup document.
The following sections provide basic instruc-
tions for configuring OMS. For more detailed in-
formation, refer to the online OMS Guide in-
stalled with Pro Tools.
Configuring a New Studio Setup
(First-Time OMS Users Only)
Before configuring OMS, make sure your MIDI
interfaces and devices are connected according
to the manufacture’s instructions and turned
on.
To configure a New Studio Setup in OMS:
1 Launch the OMS Setup application. If OMS
has not yet been configured, you’ll be prompted
to configure a New Studio Setup. Click OK.
2 Select whether your MIDI interface is con-
nected to the Modem or Printer port. If using a
USB or PCI-based MIDI interface, leave both
ports unchecked. Click Search.
