Chapter 24: Time Code Synchronization 357
11 In the Sync Options dialog, set the Re-
ceive Sync Mode pop-up to MTC/Machine
Control, set the Receive Sync Device pop-
up to IAC1, and enable Remote Start.
(Leave the Send Sync option set to None.)
Also, configure the frame rate to match
your Pro Tools session. Click OK to close
the Sync Options dialog.
12 Set the sequence start time (01:00:00:00
for example). 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 the Play button. Vision should
now be ready to start synchronized play-
back.
In Pro Tools:
15 Choose MIDI > Enable Input Devices.
Select the IAC bus transmitting the MMC
messages and click OK.
16 Choose Operations > Active in Back-
ground.
17 Choose Windows > Show Session Setup,
and choose the appropriate frame rate and
SMPTE Start Frame to match the offset
(start time) in Vision.
18 In the Output Time Code section of the
Session Setup Window, enable the MTC to
Port option. In the pop-up menu just be-
low the MTC to Port option, choose IAC1.
You can now close the Session Setup Win-
dow, or leave it open (settings are active as
soon as they are enabled in the Session
Setup Window).
19 Next, choose Setups > Peripherals, and
open the Synchronization page of the Pe-
ripherals dialog.
20 First, select Generic MTC Reader as the
synchronization device, and select Any as
the port.
21 Next, click to Enable Control of
Pro Tools via MMC, and set the ID to 0.
▲ If MMC is also currently enabled in the
Pro Tools Peripherals > Machine Control dia-
log, you must assign a unique ID number in
both of the corresponding MMC ID# fields. If
not, an MMC feedback loop will occur. This can
also happen if you use the default “broadcast
to all” ID number of 127 in both places. If you
are only slaving Pro Tools to a sequencer via
MMC, without an external device requiring
MMC from Pro Tools, you should disable MMC
entirely in the Machine Control window.
In Vision:
22 Engage any of the following Transport
functions in Vision: Play, Stop, Fast For-
ward, Rewind, Record, or Locate (Cue). Vi-
sion will send MIDI Machine Control
commands to Pro Tools via the IAC bus,
and Pro Tools will follow.
When starting and stopping playback in
the sequencer, Vision will send out loca-
tion information to Pro Tools via MIDI Ma-
chine Control commands. Pro Tools will
then cue to the location, begin playback,
and in turn send MIDI Time Code back to
Vision. Vision will then lock to the MIDI
Time Code from Pro Tools for synchro-
nized playback.
