MIDI Synchronization

MIDI Synchronization, or MIDI Sync, is usually used to synchronize

SONAR with drum machines, stand-alone MIDI hardware sequencers, and

sequencers built into MIDI keyboards. SONAR can slave to MIDI Sync, and

can send MIDI Sync on multiple output ports.

When MIDI devices are synched, the master device sends messages to all

other devices to start and stop playback and to keep all the devices in sync.

To change the tempo of a project, you adjust the tempo on the master

device. The playback tempo on all slave devices is then set automatically.

The following MIDI messages are sent by the master device to support

MIDI Sync:

Message… How it is used…

Start This message tells slave devices to start playing from the

beginning of the currently loaded sequence.

Stop This message tells slave devices to stop playback.

Continue This message tells slave devices to continue playing from

the current location in the currently loaded sequence.

Song Position Pointer

(SPP)

This message tells slave devices to change the current

location to the designated point in the project. SONAR

normally issues an SPP message immediately prior to any

Start or Continue message.

Clock The master sends clock messages to each slave device at

the rate of 24 per quarter note. The slave devices use

these messages to establish the tempo and stay in sync.
