MIDI Machine Control (MMC)
This section allows you to control MMC devices from SONAR, and has the following options;
• Transmit MMC. Choosing this option causes SONAR to send standard MMC commands such
as start, stop, rewind, etc., to any MMC devices that are connected to your computer.
• Timecode Master’s Unit ID. If you have several MMC devices connected to your computer,
for example three ADAT machines, one of them will be the timing master, and SONAR and the
other MMC devices will slave to its timing. Fill in the ID number of the master MMC device, so
that SONAR’s MMC commands go to the right device.
Other Options
• Zero Controllers When Play Stops. If you choose this option, SONAR sets the controller
values of the pitch wheel, the sustain pedal, and the modulation wheel on all 16 MIDI channels to
zero. It also sends a “zero all continuous controllers” MIDI message which turns off other
continuous controllers on newer synthesizers. If you experience frequent stuck notes when
playback stops, try checking this option.
• Patch/Controller Searchback Before Play Starts. If you choose this option, SONAR finds and
sends the most recent patch changes, wheel events, and pedal events before starting playback.
This way, all settings are correct even if you start playback at an arbitrary point in the project.

Send MIDI Sync
When SONAR is the timing master in a master/slave synchronized setup, use this section to set
MIDI Sync options:
• Transmit MIDI Start/Continue/Stop/Clock. Choosing this option causes SONAR to tell the
slave when to start, when to continue, when to stop, and what timing data to go by (SONAR’s).
• Use Start, Never Continue (greyed-out unless you check the previous option). Choosing
this option causes SONAR to only transmit MIDI Start messages every time it restarts, even in the
middle of a song. If you have a drum machine slaved to SONAR, and the drum machine is playing
looped patterns, you probably want it to start at the beginning of its loop whenever SONAR
restarts, even if SONAR restarts from the middle of a song.
• Transmit MIDI Song Position Pointer (SPP). Choosing this option causes SONAR to send an
SPP message before starting or continuing playback. If you are using a drum machine as
described above, you might want to disable this option.
• Locate Delay for SPP Recipient. Some older MIDI devices take a small amount of time to
respond to SPP messages. This option causes SONAR to delay briefly after sending an SPP
message, in order to give the slave device time to respond. The delay is in 1/18ths of a
second. Enter 1 for a 1/18th second delay, 2 for 2/18ths of a second, or 18 for a full second
delay.
• MIDI Sync Output Ports. Choose the outputs that your slave devices are connected to.
