Chapter 24: Time Code Synchronization 355
4 Configure the ADAT OMS device by dou-
ble-clicking its icon. Leave Is Controller
and Is Multitimbral unchecked (disabled).
Enable both Sends and Receives MIDI Time
Code and MIDI Machine Control. You do
not need to have any Receive channels en-
abled.
5 Save/Make Current and then close the
new OMS Studio Setup.
In Pro Tools
6 Choose Setups > Peripherals and click
Synchronization.
7 Select Generic MTC Reader as the Syn-
chronization device (this represents the
64X), then select the port to which your
MIDI Interface is connected to (in this ex-
ample, the port choice would appear as
“Studio64X / Printer.”)
8 Open the Machine Control window of
the Peripherals dialog. In the MIDI Ma-
chine Control section, enable MMC, then
select JLCooper DataMaster as the Send To
destination.
9 Set the ID to 127 (this is the “broadcast to
all” setting, and the Pro Tools default set-
ting for MMC device ID).
10 Choose Windows > Show Session Setup.
11 In the Session Setup Window, set the
frame rate and start frame as appropriate.
12 Enable the MTC to Port option (click in
the box so that it is enabled), then select JL-
Cooper DataMaster in the pop-up next to
MTC to Port. This routes MIDI Time Code
from Pro Tools to the JLCooper. device,
which then sends the data on to the ADAT.
13 Close the Session Setup window.
14 Click Play or press the Spacebar. The
ADAT will cue to the play point and begin
playing back in sync with Pro Tools. You do
not need to put Pro Tools online to control
the ADAT.
15 To control the ADAT from the Pro Tools
Transport, select MMC from the Transport
pop-up (in the Transport window). Pressing
Play, Rewind, FFWD, RTZ or Go To End will
cause the ADAT to respond accordingly.
External Hardware Configuration
This example uses the JL Cooper Data-
MASTER, which must be configured cor-
rectly for the above to work. Configure the
ADAT as a slave (not master), enable MTC
as the sync source, and enable MIDI Ma-
chine Control. The ADAT must be set to In-
ternal mode. Consult the documentation
that came with these devices for more de-
tails. If you are using a Digidesign ADAT
Bridge I/O, refer to the ADAT Bridge I/O
User’s Guide for additional information.
Syncing Pro Tools to an
OMS-Compatible
Sequencer using MMC
(Macintosh Only)
You can “lock” a MIDI sequencer to
Pro Tools for synchronized operation,
while using the sequencer as the transport
and location master. In this case, Pro Tools
is still the system clock master, while the
sequencer is the transport/location master.
