vice, you may need to use a MIDI offset. In this
example, it will usually take at least 5 ms to trig-
ger the MIDI notes, and it could take even
longer, depending on the MIDI device.
You can measure the latency for a MIDI device
assigned to a MIDI track by recording its audio
output back into Pro Tools. Compare the sam-
ple locations for the recorded audio events
against the original MIDI notes to calculate the
latency.
To configure a MIDI track offset for a track:
1 Choose Windows > Show MIDI Track Offsets.
2 Click in the Sample Offset column for the
MIDI track and enter the number of samples
(–10,000 to 10,000) for the offset. A negative
value causes the MIDI tracks to play back earlier
than the audio tracks; a positive value causes the
MIDI tracks to play back later.
The equivalent offset in milliseconds is dis-
played in the Msec Offset column. This value
cannot be edited, but updates when a new value
is entered in the SMPTE Offset column.
3 Press Enter (Windows) or Return (Macintosh)
to accept the entered offset value.
To reset all offsets for all MIDI tracks, click the
Reset button in the upper left of the window.
Stuck Notes
If you encounter stuck notes with any of your
MIDI devices, you can silence them with the All
Notes Off command.
To turn off all stuck notes:
■ Choose MIDI > All Notes Off.
