Chapter 6: Remote 9-Pin Deck Emulation Mode (Configuration and Operation) 39
The time code master is defined by the machine
controller. If Pro Tools is not the time code mas-
ter, it needs additional time to behave as a
proper remote machine as time code slave. This
time is defined using the Delay Before Play set-
ting:
• When Delay After Play is set to zero,
Pro Tools is set up to function properly as
the time code master. When online, Pro
Tools locates, then plays when it gets a play
command.
• When Delay After Play is set towards 30
frames, another machine is the time code
master. When online, Pro Tools locates,
sends time code position responses, and
when its time code lines up with the time
code master device, then goes into play in
sync with the time code master device.
To set the time code master in Full Remote mode:
1 Choose Setup > Preferences, and click the Ma-
chine Control tab.
2 In the Remote Mode section, do one of the fol-
lowing:
• Set Delay After Play is set to zero, to prepare
Pro Tools to behave quickly as the time
code master.
• Set Delay After Play towards 30 frames, to
set up Pro Tools to behave properly as a
time code slave device by delaying play-
back until its time code can properly syn-
chronize first.
Chase LTC
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 time code, you can
avoid the waiting (and tape wear) that occurs
while a machine transport locates and bumps
tape to the cue point.
In Remote 9-Pin Deck Emulation mode, when
the Transport window is online and Chase LTC
is enabled, the Transport Master selector shows
Transport = Remote LTC, and Pro Tools is now
in Remote /LTC Chase mode. Pro Tools also
communicates record status to the machine.
Receiving Commands While Chase LTC is
Enabled or Disabled
When Chase LTC is enabled and the system is
online, Pro Tools waits until it receives only spe-
cific transport record and track record com-
mands from the machine. When Chase LTC is
not enabled, Pro Tools listens to all transport
commands coming through the serial connec-
tion, including bump and crawl commands nec-
essary for a tape machine to locate.
Scrubbing and Chase LTC
The Chase LTC option does not affect scrub-
bing. Pro Tools video playback will always re-
spond to locate and scrubbing command, even
if Chase LTC is enabled.
Generally, delay should only be added if
Pro Tools is having problems starting and
locking to a machine during playback or
record. For example, if Pro Tools tries to
lock, and the Transport window lights go
from play to shuttle or fast-forward to re-
wind many times before locking, you should
increase the Delay After Play setting by a
few frames.
