Sonar as the slave

When Sonar is slaved to an external MIDI device, the following changes occur:

When you click the Play or Record button, a message (Waiting for MIDI Sync) is displayed in the status bar. When you start your external device, Sonar will follow.

If you change the tempo using an external device, the SMPTE time code display in Sonar will be incorrect.

Sonar will not transmit MIDI Start, Continue, Stop, and Clock messages.

Digital audio will play back, but not necessarily in sync.

To use MIDI Sync with Sonar as the slave

1.	Configure the external MIDI device you want to use as the master device to transmit MIDI Sync.

2.	Configure external slave devices to receive MIDI Sync.

3.	Go to Edit > Preferences > MIDI Devices and make sure the MIDI input port that connects to the MIDI Sync master is selected.

4.	In the Preferences dialog box, go to Project - Clock and set Source to MIDI Sync.

5.	In the Preferences dialog box, go to Project - MIDI and make sure Transmit MIDI Start/Continue/Stop/Clock is not selected, and clear any selected ports under MIDI Sync Output Ports. Sonar will receive sync data from the sync master, and should therefore not transmit any sync data.

6.	In the Preferences dialog box, go to Audio - Sync and Caching and select Always switch clock source and start and Maintain current clock source and wait for timecode. This will prevent Sonar from switching back to its internal clock.

7.

Click OK.

From now on, Sonar starts playback and recording only after the appropriate message is received from the master device.
