SYNC I/O (or, using USD) is automatically en-
abled. This is required for Pro Tools to lock to
the video reference with frame edge accuracy.

Chase LTC
Remote 9-Pin Deck Emulation mode lets a mas-
ter device control Pro Tools track and Transport
arming. In standard Remote 9-Pin Deck Emula-
tion mode, Pro Tools serves as the time code
master device while simultaneously responding
to 9-pin transport and track arming commands.
When Chase LTC is enabled, Pro Tools can still
respond to 9-pin track arming and record com-
mands, but chase incoming LTC instead of be-
ing the time code master device. By slaving
Pro Tools to the LTC source instead of slaving
the machine to Pro Tools time code, you can
avoid waiting (and tape wear) while a machine
transport locates and bumps tape to the cue
point.
When Chase LTC is enabled, the Transport mas-
ter selector shows Transport = Remote LTC.
Pro Tools also communicates record status to
the machine.
Receiving Commands While Chase LTC is
Enabled
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 will listen to all transport
commands arriving 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.
Alternate Machine Types
By default, MachineControl lets Pro Tools emu-
late a Sony BVW-75. If you use a machine that
follows a different 9-pin command set, you can
configure Pro Tools for its machine description
by selecting it as the 9-Pin Remote device in the
Machine Control page of the Peripherals dialog.
