corresponding to the rhythm pattern will be transmitted on the MIDI channel that is
specified for the rhythm guide.
Status Second Third
9nH mmH llH
n = MIDI Channel No. : 0H - FH (ch.1 - ch.16)
mm = Note No. : 00H - 7FH (0 - 127)
ll = Velocity : 01H - 7FH (1 - 127)
●Note Off
If the MIDI parameter “RhyMIDI ch” is set to “1–16,” note numbers corresponding to the
rhythm pattern will be transmitted on the MIDI channel specified for the rhythm guide.

■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”.
