About OMS
Voice Editor uses the OMS (Open Music System) to transfer MIDI data to an external MIDI
device. OMS is a system extension that goes in the Mac OS System folder, designed to manage
the MIDI data stream (input & output) in a computer, to enable MIDI data transfer between MIDI
software and hardware attached to the computer. OMS is a de facto standard of the MIDI
environment under the Mac OS, and various music software manufacturers have released OMS-
compatible sequencer and other software.
OMS has the following merits:
• As OMS-compatible MIDI applications communicate with various MIDI devices via OMS, it is
no longer necessary for you to set up multiple MIDI drivers for those applications. Thus, you
can avoid conflicts between different drivers with the same purpose (MIDI control).
• Once a Studio Setup is read in OMS, any OMS-compatible application will be aware of it, even
if you need to reconfigure the routing of the MIDI data stream or change the current Studio
Setup. OMS-compatible applications will commonly recognize the new configuration.
• You can have different Studio Setups to choose from, letting you instantly switch to a different
MIDI routing (patches between MIDI devices and software).
• Every time the OMS Setup application is opened, any MIDI device connected to the computer
is automatically detected, and its icon appears with a current MIDI status (channel number,
port number, patches, etc.). Once devices are properly configured with OMS Setup, you don't
need to worry about the status.
• OMS can drive various MIDI interfaces, including the standard type (16 channels) and the
multi-port type (16 channels per port). If you use a multi-port type, you can control over 16
channels simultaneously via OMS.
