MachineControl Guide10
After you select a port, Pro Tools automatically
polls the port to see what kind of machine is
connected. This process is referred to as auto de-
tection. One of the following will occur:
If the machine is recognized, Pro Tools loads
the corresponding Machine Type and Node.
This includes the corresponding track layout
and automatically enters the name of that ma-
chine into the Pro Tools Machine Track Arming
window.
If the machine is not recognized, the
generic1” personality is automatically loaded.
6 If you want to choose a different machine pro-
file (for example, to use a different track layout),
choose it from the Node pop-up menu.
7 Set the machine pre-roll (see “Machine Pre-
Roll” on page 10 for more information).
8 If you are using a SYNC I/O with
Pro Tools|HD, and if you have two machines
connected to the two 9-pin Out ports on the
SYNC I/O, repeat the above steps for the second
machine. See “Selecting Machines in Serial Con-
trol Mode” on page 17 for more information.
9 Click OK to close the Peripherals dialog box.
To configure and use MachineControl features
in Pro Tools, see Chapter 3, “Serial Control
Mode and Transport Control.”
Machine Pre-Roll
You can set a variable amount of machine pre-
roll to account for the time it may take the ma-
chine to achieve servo lock. Shorter pre-roll val-
ues are usually better for non-linear machines.
Longer pre-roll values are usually better for older
tape transports.
The Machine pre-roll value is added to any pre-
roll specified in the Pro Tools Transport window.
To set MachineControl pre-roll:
1 In Pro Tools, choose Setups > Peripherals, and
click the Machine Control tab.
2 In the 9-pin Serial section, enter the number
of frames of pre-roll.
3 Click OK.
Pro Tools lets you define and save custom
machine profiles. See Chapter 5, “Remote
Track Arming” for more information.
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.
