MIDI Time Code
Use utility programs that come with
your MIDI interface to make sure that
the time code stripe is being received

Code Sync option). Check the MIDI
interface settings to make sure that
MIDI Time Code is being generated.
The frame rate is set incorrectly The frame rate on the stripe must
match the frame rate you set in
SONAR.
The offset is set incorrectly The offset you enter in SONAR must
match the start time of recorded
material on the tape.
SONAR is not configured
