Chapter 24: Time Code Synchronization 351
Syncing a Sequencer to
Pro Tools in Windows
To synchronize Pro Tools to a Windows
sequencer:
1 Make sure your MIDI interface is cor-
rectly installed and configured. You must
do this before proceeding.
2 Choose one pair of input/output ports
on your MIDI interface to use as your sync
“loop” for application-to-application MIDI
communication.
3 Connect a MIDI cable from that port’s
output to the same port’s input (for exam-
ple, port 1 out to port 1 in).
4 In Pro Tools, select the appropriate in/out
ports when making your selections for
MIDI source and/or destination ports.
• If you are slaving your sequencer to
Pro Tools, select the appropriate port in
the Session Setup window’s MTC to Port
pop-up menu.
• If you are slaving Pro Tools to your se-
quencer, select the appropriate port in
the Pro Tools Peripherals > Synchroniza-
tion window.
5 In your sequencer, select the appropriate
in/out ports for MTC source/destination.
Using MIDI Machine
Control
Pro Tools provides the capability to trans-
mit location information to external de-
vices, and to control their transports, using
MIDI Machine Control (MMC).
Controlling External Devices
using MMC
Any device which supports MMC (such as
an Alesis ADAT or Tascam DA-88) can be
controlled directly from within Pro Tools,
with either the device or Pro Tools acting as
clock master.
The external devices supported by
Pro Tools implement “open loop” commu-
nications only. Because of this, while
Pro Tools is the transport master, any di-
rect operation of the receiving device’s
transport will not be communicated back
to Pro Tools. Instead, you can use the
Transport pop-up to select the external de-
vice (MMC in the pop-up) and use the
Pro Tools on-screen transport controls to
drive the device.
Pro Tools does not support remote track
arming of MMC-controlled external de-
vices. You need to manually arm tracks for
recording on the external device.
✽ Digidesign’s MachineControl option does
support remote track arming. See “Remote
Track Arming” on page 353.
