6 In the OMS Studio Setup window, define
an IAC Bus by double-clicking the IAC
Driver icon, and typing IAC1, for example,
in the first field (this provides a unique
name for this particular IAC bus).
In Opcode Vision:
7 In the Enable Input Devices window in
the Setups menu, enable IAC1 (the IAC bus
you defined/named previously).
8 Choose Operations > Sync Options.
9 In the Sync Options dialog, set the Re-
ceive Sync Mode pop-up to MIDI Time
Code.
10 Next, set the Receive Sync Device pop-
up to IAC1.
11 Select the SMPTE Format (frame rate)
that will match Pro Tools (29.97 non drop,
for example). Click OK to close the Sync
Options dialog.
12 In Vision’s Control bar, set the sequence
start time, for example, at one hour
(01:00:00:00). The Offset at the top of the
Sequence window should usually match
the Offset in Pro Tools.
13 Select Wait Note in the Transport.
14 Click Play or press the Spacebar. Vision
should now be ready to start synchronized
playback.
In Pro Tools:
15 Select Operations > Active in Back-
ground.
16 Choose Windows > Show Session Setup.
17 In the Session Setup window, choose an
appropriate frame rate.
18 Select the SMPTE Start Frame to match
the offset in Vision. If the sequence starts at
the very beginning you could set the
Pro Tools Session to start earlier (for exam-
ple, at 00:59:58:00) to allow some pre-roll.
19 Enable the MTC to Port option in the
Output Time Code box. In the pop-up
menu just below the MTC to Port option,
choose IAC1.
20 Close the Session Setup window.
21 Click Play or press the Spacebar to start
playback. Pro Tools will send MIDI Time
Code to Vision via the IAC port and trigger
synchronized playback for Vision. Click
Stop in the Transport or press the Space bar
again to stop playback.
Once synchronized playback is operating
correctly, you can record new takes in
Pro Tools while listening to MIDI playback
from your sequencer. Follow the procedure
described above for synchronized play-
back, then record new material in
Pro Tools by following the recording proce-
dures in the Recording section of this man-
ual.
You should also be able to record new MIDI
tracks while the sequencer is slaved to
Pro Tools. See your sequencer documenta-
tion for details on recording while the se-
quencer is in an external synchronization
mode.
