To Use SONAR as the Master MTC Generator
1. Configure the clocks on each external device that you want to synchronize to receive SMPTE/MTC.
Make sure they're connected to MIDI outputs from your computer or MIDI interface.
2. Click or
Sync toolbar, use the View-Toolbars-Sync command).
3. Use the Options-Project command to open the Project Options dialog.
4. On the Sync tab, check the Transmit MTC checkbox (you can also click the Transmit MTC button
on the Sync toolbar).
5. In the Frame Rate field (it's just below the Transmit MTC checkbox), choose the frame rate that
your project uses (see "Frame Rates" on page 533, if necessary).
6. In the MTC Output Ports field, check off the outputs that you want to send MTC on (the outputs
your external devices are connected to).
7. Click OK.
SONAR saves your sync and MTC output port settings with your project. However, output ports are
saved by their number only, not their name. Their number is determined by the order in which they
appear in the MIDI Devices dialog under Outputs (Options-MIDI Devices command). If you change
the order of devices in this dialog, the MTC output ports in your project will retain the same numbers,
but those numbers will now refer to different outputs. Also, if you reduce the number of highlighted
outputs in the MIDI Devices dialog, and the MTC ports you chose have higher numbers than what are
currently highlighted in the MIDI Devices dialog, SONAR does not substitute new port numbers. Also,
SONAR does not send MTC if SONAR's Tempo Ratio buttons are set to any value other than 1.
To Configure SONAR to Sync to SMPTE/MTC
1. Click the SMPTE/MTC mode button
2. Select Options-Global and click on the Timecode tab.
3. Select one of the following options:
• 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.
