Preferences for Serial Deck
Control Mode
You can configure preferences for MachineCon-
trol playback and recording in Pro Tools.
Playback Options
Machine Control Section
Machine Chases Memory Location When se-
lected, navigating to a specific location in a ses-
sion with a Memory Location causes a con-
nected transport to chase to that location.
Machine Follows Edit Insertion/Scrub When se-
lected, navigating to a specific location in a ses-
sion by moving the selection point or by scrub-
bing a track will cause a connected transport to
chase to that location.
When the connected device is a linear device
(such as a tape deck), select Linear Devices (jog) to
set Pro Tools to send jog commands.
When the connected device is a non-linear
device (such as a random-access video recorder
or another Pro Tools system), select Non-Linear
Devices (cue) to set Pro Tools to send cue com-
mands.
Machine Cues Intelligently When selected, if you
navigate to a cue point that is more than 10 sec-
onds from the current location, Pro Tools will
command a connected transport to fast wind to
the new location at full speed to within 10 sec-
onds of the cue point. Cueing will then slow to
normal speed until the point is reached. This
can significantly speed up tape cueing with cer-
tain video transports.

MachineControl Guide
Stop at Shuttle Speed Zero Causes Pro Tools to
send a Stop command whenever you stop shut-
tling. This is useful if you have a machine that
requires an explicit stop command to park cor-
rectly.
Non-Linear Transport Error Suppression When
Transport = Pro Tools, keeps Pro Tools from
sending a Stop command when taken offline.
This prevents Pro Tools from stopping any other
9-pin devices connected to the system.
Synchronization Section
Minimum Sync Delay Sets the amount of time (in
frames) for devices to achieve synchronization
"lock." This amount varies for each device.
Pro Tools lock up delay is set by entering a value
for Minimum Sync Delay in the Synchronization
page of the Preferences dialog. The lowest value
available is 15 frames. Find the shortest possible
lock-up time that your equipment can operate
at consistently, and set this as the delay value.
Delay Before Locking to Longitudinal Time
Code Sets the amount of time (in frames) for
Pro Tools to lock to incoming LTC. Use this op-
tion when locking Pro Tools to a stable time
code source (such as a non-linear machine or
LTC generator) and not a linear tape machine.
Delay Before Locking to Serial Time Code Sets
the amount of time (in frames) for Pro Tools to
wait before attempting to lock to machines that
issue servo lock messages. This setting allows
time for the servo mechanisms to achieve stable
lock.
