Testing Session Settings
To check your session and MachineControl set-
tings, place the machine in Local mode and
manually start playback on the external ma-
chine. If Pro Tools is receiving time code, the
current location will be shown in the Incoming
Time display. Be sure to reset the machine to Re-
mote mode when finished.
Incoming Time display
External Time Code Offsets
In the External Time Code Offsets section,
Pro Tools lets you compensate for devices that
are consistently offset by a fixed number of
frames (such as some color–corrected video mas-
ters), or for material that starts at a different
time than the session.
Pro Tools provides four different External Time
Code Offset settings:
• MMC (MIDI Machine Control)
• 9-Pin (Deck Control)
• Synchronization peripherals such as the
SYNC HD, SYNC I/O, or other peripherals
(such as MIDI interfaces that provide MIDI
Time Code).
• Satellite (Pro Tools with Satellite Link or
Video Satellite)
Unique values can be defined for each of these
types of offsets, or you can link all to adjust in
unison.
Positive and negative offset values can be en-
tered to offset Pro Tools time code display later
or earlier, respectively.

Sample Offset
This field lets you set an offset value for incom-
ing time code (up to the equivalent of plus or
minus one frame at the current session sample
rate). This lets you create a permanent offset to
fine-tune the point at which Pro Tools synchro-
nizes relative to incoming time code. For exam-
ple, a value of –50 makes an event in Pro Tools
occur 50 samples before the same event in the
incoming time code. Use this to compensate for
timing differences between various SMPTE-to-
MIDI Time Code converters or analog-to-digi-
tal/digital-to-analog converters.
Offsets and SYNC Time Code Display
The time code display on the front panel of the
SYNC peripheral continues to display actual in-
coming time code, regardless of any External
Time Code Offset applied in Pro Tools.
To apply an offset to an external time code source:
In the Session Setup window, enter an offset
value time in an offset field.
External Time Code Offsets in the Session Setup
window
To apply the same time code offset to all devices:
In the Session Setup window, select Link to
apply the same offset value to all devices.
