Chapter 24: Time Code Synchronization 353
7 Set a preroll time for your MMC device.
Preroll is needed to provide Pro Tools with
sufficient time to lock to the incoming
time code. This value will vary depending
on the external device. If the preroll time is
insufficient, Pro Tools may not be ready to
lock until after the current time code posi-
tion has passed.
8 Click OK to close the Peripherals dialog.
Pro Tools will now be able to control the se-
lected device’s transport.
Operating the Pro Tools Transport
with MMC
To control external devices from the
Pro Tools Transport:
■ Select either Pro Tools or MMC from the
Transport pop-up in the Pro Tools Trans-
port window. The selected item will act as
Transport Master.
When the Transport Master is set to
Pro Tools, the playback position is gov-
erned by the on-screen cursor in Pro Tools.
When the Transport Master is set to MMC,
the playback position is governed by the
external device’s play position
Machine Transport Settings
When using MMC, you can set the follow-
ing options for machine transport behavior
in the Operation page of the Preferences di-
alog.
Machine Chases Memory Location With
this option enabled, navigating to a spe-
cific location in a session with a Memory
Location causes a connected transport to
chase to that location.
Machine Follows Edit Insertion/Scrub With
this option enabled, navigating to a spe-
cific location in a session by moving the se-
lection point or by scrubbing a track causes
a connected transport to chase to that loca-
tion.
Remote Track Arming
Digidesign’s MachineControl™ option for
Pro Tools allows you to remotely arm tracks
on supported 9-pin or V-LAN decks. With-
out MachineControl, Pro Tools does not
support remote track arming of external
devices. MachineControl is a DAE Exten-
sion which allows Pro Tools to act as the
master or slave to external Sony 9-pin or V-
LAN machines, in addition to providing re-
mote track arming from within Pro Tools.
Contact your Digidesign Dealer for infor-
mation about the MachineControl option.
