MachineControl Communication Modes
MachineControl supports two machine com-
munication modes: Serial Deck Control mode and
Remote 9-Pin Deck Emulation mode.
Serial Deck Control Mode
With Serial Deck Control mode, you can use the
Pro Tools Transport window to control an exter-
nal deck.
Pro Tools Transport window
Transport
The setting of the Transport Master (located in
the Pro Tools Transport window) determines
the type of Serial Deck Control, as follows:
Transport = Pro Tools The Transport window
controls the Pro Tools Timeline. When online,
the deck locates relative to actions taken in the
Pro Tools Timeline.
Transport = Machine The Transport window
controls the machine. When Pro Tools is On-
line, the Pro Tools Timeline chases the machine.
Cueing and Pre-Roll
Pro Tools Preference settings let you optimize
MachineControl operation, including adjust-
able machine pre-roll, selectable edit and mem-
ory location chasing.
Track Arming
When the Transport Master is set to Transport =
Machine, you can arm tracks of external ma-
chines from within Pro Tools for layback and
transfer. Features include individual record en-
ables for up to 48 external tracks, with selectable
record protocol and mode. Machine profiles in-
cluded with the software let you preconfigure
track arming for many machine types.
Serial Time Code
When the Positional Reference is set to Serial
Time Code in the Session Setup window,
Pro Tools can control an external machine via
the Serial Deck Control cable. This setting also
enables Pro Tools to receive time code directly
using only the Serial Deck Control cable.
(This mode requires that the 9-pin device be ca-
pable of transmitting serial time code. It also re-
quires that the Pro Tools and the device receive
a common video reference.)
