SMPTE/MIDI Time Code Synchronization
Synchronizing Your Gear
• Ask first, then switch to clock source and start—this option prompts
SONAR to alert you when it detects a SMPTE/MTC signal, asks if
you want to sync to the incoming signal, and if you respond that you
do, switches the clock source and starts to receive the signal.
• Always switch the clock source and start—SONAR automatically
switches to the clock source of the incoming signal and begins to
receive the signal.
• Do not switch clock source, but start if in SMPTE/MTC mode—this
option automatically syncs to the incoming signal if SONAR is in
SMPTE/MTC mode.
Note: The final option, Never switch clock source, never start, should
never be used if you are attempting to sync to an external clock source.
4. Click OK.
5. Choose Options-Project, and click the Clock tab.
6. Choose the frame rate and time offset that are appropriate for your
source material.
7. Click OK to close the dialog box.
8. Choose Options-MIDI Devices to display the MIDI Devices dialog box.
9. Make sure that your MIDI interface is highlighted in the Inputs list. If
your interface also has a Sync driver, highlight that as well, then click
OK.
When SONAR is the slave, here’s how things work:
• SONAR monitors for a SMPTE/MTC signal. You are able to perform
other action in SONAR while waiting for the signal.
• Start playback on the external device. It takes about two seconds for
SONAR to lock from the time it receives time code input.
• If the time code is earlier than the start of the project (based on the time
code offset), another message (Chasing…) is displayed in the status
bar. When the time code reaches the start of the project, SONAR starts
to play in sync.
• If the time code is at or after the start of the project, SONAR starts
playback as soon as it locks to the time code.
• When the external device stops (or when the time code ends), SONAR
will stop.
