time code via the SSD. If Pro Tools detects
incoming time code on its sync peripheral,
it locks to the incoming code (as in normal
online operation).
Generating SMPTE or MIDI Time
Code Using a USD
Using a USD, Pro Tools can generate
SMPTE or MTC. You can then make
Pro Tools a master synchronization source
with other devices slaved to it.
▲ The USD cannot generate 24 FPS time code
while it is locked to a video clock signal. If you
set Pro Tools to generate 24 FPS time code
while the USD is locked to a video clock signal,
the USD will actually generate at the NTSC
color standard 29.97 Non-Drop Frame rate.
Pro Tools can generate time code at non-NTSC
frame rates if you use the USD’s internal clock
as a sync source.
To generate time code using a USD:
1 Connect the SMPTE out of the USD to
the SMPTE in connector on the device(s)
you are slaving. Refer to the Universal Slave
Driver User’s Guide to determine how to
make these connections for your system. If
you are slaving a device that recognizes
MTC and you wish to use MTC instead of
SMPTE, connect the MTC OUT connector
of the USD to the MIDI IN connector of the
slaved device.
2 Make sure your USD is powered on.
3 In Pro Tools, choose Setups > Peripherals
and click Synchronization.
4 Select USD from the Device pop-up.
5 Select the Macintosh port or Windows se-
rial port where the USD is connected.
6 Choose Windows > Show Session Setup,
and choose the appropriate frame and sam-
ple rates.
7 In the Generate Time Code field, select
the “Using USD” option.

menu to show USD modes. Select the de-
