Digital Timepiece & OMS
OVERVIEW
The procedures in this chapter apply to OMS for
Macintosh version 2.3.1 or later only.
OMS is a Macintosh system extension that —
among other things — allows OMS-compatible
software to establish MIDI communication with
the Digital Timepiece. For example, a sequencer or
other OMS-compatible program that supports
MIDI Machine Control could be a transport
master over the Digital Timepiece. This would
allow you to control the Digital Timepiece — and
all devices connected to it — from the OMS
program. An example of this type of program is the
OMS applet called “AV Controls”, which provides
basic transport control over the Digital Timepiece.
This chapter explains how to set up OMS for the
Digital Timepiece. It also explains how to run OMS
programs simultaneously with ClockWorks, which
you will want to do because ClockWorks gives you
instant access to many crucial features on the
devices connected to the Digital Timepiece.

CLOCKWORKS AND OMS
Ideally, you will want to use the Digital Timepiece
software, ClockWorks, along with your OMS
applications because ClockWorks provides remote
control of the following advanced features in the
devices connected to your Digital Timepiece:
■
Record-arming and disarming specific tracks in
a device
■
Setting a SMPTE offset for each device
■
Setting individual track offsets for ADATs and
DA-88s
■
Choose between analog or digital input on a
device
■
Setting the monitor mode for a device ( All or
Auto, which monitors record-enabled inputs only)
■
Setting the video record mode on 9-pin
compatible video decks ( Insert , Assemble , or
Crash/Full Record )
There are two ways for OMS and ClockWorks to
run simultaneously on a Macintosh:
■
Option 1: both share a Macintosh serial port
OR
■
Option 2: each uses its own separate Macintosh
serial port
The pros and cons of each approach are discussed
briefly in the next two sections.
A special note for Pro Tools users
If you use Pro Tools, be sure to read chapter 12,
“Digital Timepiece & Pro Tools” (page 83) for an
important third option for dealing with OMS:
using OMS emulation in FreeMIDI.
