Selecting Full Remote Mode or
Remote/LTC Chase Mode
Remote 9-Pin Deck Emulation mode lets a master
device control Pro Tools track and transport arm-
ing.
When Pro Tools is in Remote mode, Remote 9-pin
Deck Emulation operates in Full Remote mode or
in Remote/LTC Chase mode.
When Pro Tools is not in Remote mode, it ignores
commands from the 9-pin machine controller.
Pro Tools responds only to requests from the 9-pin
machine controller for machine type and status,
and responds that it is in Local mode.
Full Remote Mode
In Remote 9-Pin Deck Emulation mode, when
Pro Tools is in Remote mode and Chase LTC is not
enabled, Pro Tools is in one of the two following
states:
• When the
Delay after Play Command preference
is set to zero, Pro Tools is set to function as the
timecode master. Pro Tools locates, then plays
when it gets a play command.
• When the
Delay after Play Command preference
is set towards 30 frames, another machine is the
timecode master. Pro Tools locates, sends time-
code position responses, and when its timecode
lines up with the timecode master device, goes
into play in sync with the timecode master de-
vice.
To set the timecode master in Full Remote mode:
1 Choose Setup > Preferences, and click the
Synchronization tab.
2 In the Remote Mode section, do one of the
following:
•Set the
Delay after Play Command preference to
zero, to set Pro Tools to behave as the timecode
master.
• Set the
Delay after Play Command preference
towards 30 frames, to set Pro Tools to behave as
a timecode slave device, by delaying playback
until its timecode can properly synchronize.
Remote/LTC Chase Mode
When Chase LTC is enabled, Pro Tools can still
respond to track arming and record commands.
However, Pro Tools will chase incoming LTC in-
stead of behaving as a master or slave device with
the machine controller. By slaving Pro Tools to the
LTC source instead of slaving the machine to
Pro Tools timecode, you can avoid the waiting
(and tape wear) that occurs while a machine trans-
port locates and bumps tape to the cue point.
In Remote 9-Pin Deck Emulation mode, when
Pro Tools is in Remote Mode and Chase LTC is
enabled, it communicates record status to the ma-
chine.
Receiving Commands While Chase LTC is
Enabled or Disabled
When Chase LTC is enabled, Pro Tools waits until
it receives only specific transport record and track
record commands from the machine.
When
Chase LTC is not enabled, Pro Tools listens
to all transport commands coming through the se-
rial connection, including bump and crawl com-
mands necessary for a tape machine to locate.
Generally, delay should only be added if
Pro Tools is having problems starting and
locking to a machine during playback or re-
cord. For example, if Pro Tools tries to lock,
and the Transport window lights go from play
to shuttle or fast-forward to rewind many
times before locking, you should increase the
Delay After Play setting by a few frames.
