Roland Using MMC, Setting the MTC offset, Operating MMC-compatibledevices with the BR-864

Synchronizing with MIDI devices

Setting the MTC offset

The offset sets the time required to align the song playback and MTC timing when synchronizing an external device using MTC from the BR-864.

1.Press [UTILITY].

2.Press CURSOR [ ] [ ] to move the cursor to “SYNC,” and press [ENTER].

3.Press CURSOR [ ] [ ] to select “Offset,” and turn the TIME/VALUE dial to set the time offset.

The offset is set as the difference between the “time to which to align the MTC timing” and the “time to which to align the song timing.” For example, you want to have the external device play back with the MTC timing shown below when the song timing reaches “01h00m00s00,” then set the offset as follows.

Song Timing	MTC for	Offset Setting
	External Device
01h00m00s00	01h30m00s00	00h30m00s00
01h00m00s00	00h30m00s00	23h30m00s00

4.Press [UTILITY] (or press [EXIT] repeatedly) to return to the Play screen.

*During updating, “Keep power on!” appears in the upper line of the display, while the lower line shows what is being processed.

Using MMC

MMC stands for “MIDI Machine Control.” This is a protocol that uses MIDI System Exclusive messages to remotely control multiple recording devices from one device. Your BR- 864 supports the MMC protocol.

By using MMC, your BR-864 can send commands such as PLAY, STOP, and FF to connected MIDI devices to operate them.

Some MIDI devices do not support the BR-864’s MMC functionality. If so, it will not be possible to operate them from the BR-864 using the procedures described here. For details on the MMC functionality supported by the BR-864, read “MIDI Implementation” (p. 185).

Operating MMC-compatible devices with the BR-864

This section explains how to make settings for synchronizing the playback with a computer-based sequencer program that supports MMC and MTC. Make connections as shown in the diagram below.

MIDI IN

MIDI OUT

The BR-864 will be the master for MMC and MTC.

Follow the procedure given below to operate the play, stop, fast-forward and other functions of a sequencer program with the BR-864.

1.Press [UTILITY].

2.Press CURSOR [ ] [ ] to move the cursor to “SYNC,” and press [ENTER].
