PRO TOOLS, CLOCKWORKS, OMS & FREEMIDI
MIDI communication between Pro Tools software
and the Digital Timepiece is essential. The two
synchronize with one another via MIDI Time
Code. Further, you may wish to include MIDI
sequencing activities during your Pro Tools
sessions by playing back MIDI sequences directly
within Pro Tools or by playing them from a MIDI
sequencer running concurrently with Pro Tools.
ClockWorks also requires MIDI communication
with the Digital Timepiece. In fact, you may often
want to run ClockWorks simultaneously with Pro
Tools so that you have complete remote control of
the Digital Timepiece and the settings in the
devices connected to it, such as SMPTE offsets on
MMC devices and track offsets on your ADATs and
DA-88s.
For MIDI communication, Pro Tools relies on
OMS. On the other hand, ClockWorks relies on
FreeMIDI (as do Performer and Digital Performer,
if you are using them). Fortunately, you can easily
install and use both MIDI operating systems as
described in the previous chapter.
FreeMIDI Version 1.33 or higher, however, offers
another possibility: OMS emulation in FreeMIDI.
This scenario might be even more convenient for
you, depending on how you work with Pro Tools.
In this scenario, you remove OMS entirely from
your system, turn on OMS emulation in FreeMIDI,
and run Pro Tools under FreeMIDI’s OMS
emulation.
OMS versus OMS emulation
In summary, your two choices are:
■
Run both OMS and FreeMIDI as described in
the previous chapter
OR
■
Run FreeMIDI by itself and operate Pro Tools
under FreeMIDI’s OMS emulation
Which way should you go? The decision is mostly a
matter of convenience. Things will work fine —
with a few minor trade-offs — either way. Perhaps
the most important factor to consider is MIDI
sequencing: do you need to play MIDI simulta-
neously with Pro Tools? If so, you either need to
play MIDI sequences from within Pro Tools
(requires OMS), or run a sequencer simulta-
neously. If you want to use Performer or Digital
Performer, it will be more convenient for you to use
FreeMIDI and OMS emulation. If you are using an
OMS sequencer, you will be better off using OMS.
Summary
It will be more convenient for you to run Pro Tools
under FreeMIDI’s OMS emulation if:
■
You are using Pro Tools and ClockWorks by
themselves, and you don’t intend to play MIDI
sequences, either from Pro Tools or another
sequencer
OR
■
You intend to use Performer (or Digital
Performer) with Pro Tools for MIDI playback
On the other hand, you’ll need to use OMS instead
if:
■
You want to play back MIDI sequences directly
from within Pro Tools
OR
■
You intend to use an OMS-compatible sequencer
with Pro Tools for MIDI playback
After you decide, refer to the following section that
applies to you.
