Machine Auto-detection
If the machine is recognized, Pro Tools loads the
corresponding Machine Type and Node, as well
as the corresponding track layout and automat-
ically enters the name of that machine into the
Pro Tools Machine Track Arming window.
If the machine isn’t recognized, the generic1
personality is loaded.
5 If necessary, select the appropriate machine
type (Sony 9-pin or V-LAN) from the Machine
Type pop-up menu.
Machine Pre-Roll
You can set a variable amount of Machine pre-
roll to account for any time it may take the ma-
chine to achieve servo lock. Set this value low
for non-linear machines (including the DoReMi
V1, for example). Longer pre-roll values may
work better for some older tape transports.
The Machine pre-roll value is added to any per-
roll specified in the Pro Tools Transport window
To set MachineControl pre-roll:
1 In Pro Tools, choose Setups > Peripherals, and
select Machine Control.
2 In the 9-pin serial section, enter the desired
number of frames of pre-roll.
3 Click OK to close this dialog.
Pro Tools retains this Peripherals configuration
unless you change or disconnect it.
Machine Remote or External Mode
Be sure to set your machine-controllable device
to “remote” or “ext” mode to receive the 9-pin
or V-LAN information. These options should be
available from the main control panel of your
machine, or the main menus of its interface. If
all other Pro Tools machine communication is
established and the machine is not in Remote
mode, Pro Tools will indicate machine “local”
mode and display the message “Cannot Estab-
lish Sync” in the status display.
MachineControl enabled (G4 shown).
Do not use the designated machine port for
any other function (such as time code or
MIDI metronome). Make sure that 9-pin or
V-LAN is the only communication on the
selected port.
