Preroll
The Preroll setting lets you specify a variable
amount of machine preroll to account for the time
it may take the machine to achieve servo lock.
Shorter preroll values are usually better for non-
linear machines. Longer preroll values are usually
better for older tape transports. The Machine pre-
roll value is added to any preroll specified in the
Transport window.
9-Pin Remote (Deck Emulation)
(Avid HDX, Pro Tools|HD, and HD Native
Systems with MachineControl Only)
The 9-Pin Remote (Deck Emulation) settings let
you configure Pro Tools for 9-Pin Remote (Deck
Emulation) mode. This mode makes Pro Tools op-
erate as a virtual tape deck, supporting most stan-
dard Sony P2 9-pin commands. By default,
Pro Tools emulates a Sony BVW-75 model video
deck. You can also configure Pro Tools to emulate
other machines.
Enable
When the Enable option is selected, Pro Tools is in
9-Pin Remote (Deck Emulation) mode.
Port
The Port setting lets you select the 9-pin Machine-
Control port. The available choices depend on
your platform and configuration
Machine Type
The Machine Type setting lets you select the ma-
chine description for specific machine controllers
(such as the Soundmaster ATOM). By default,
Pro Tools emulates a Sony BVW-75.
Chase LTC
When Chase LTC is enabled, Pro Tools still re-
sponds 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.
MIDI Controllers
The MIDI Controllers page lets you configure up
to four different MIDI controllers for Pro Tools.
Number and Color
The number of the row indicates the order of the
selected controllers. The color corresponds to the
controller focus around Pro Tools track and plug-
in controls.
