System Common Messages

MIDI Time Code Quarter Frame Messages

If the Sync parameter “Syn Gen” is set to “MTC,” quarter frame messages of the time code
type specified by “MTC Type” will be transmitted when the BR-864 is running (recording or
playing). The transmitted time counts are summed to “SMPTE (MTC) Offset Time” as the
song top is “00:00:00:00”.
