Controlling the MD4S by MMC
MMC (MIDI Machine Control) is a type of MIDI message that allows the transport of an
audio/video recorder etc. to be controlled by an external MIDI device. Since the MD4S is able
to receive MMC, an MMC-compatible MIDI sequencer or other device can control the trans-
port of the MD4S. In this case, the device that transmits MMC data will be the MMC Master,
and the device that receives MMC data will be the MMC Slave.
The MD4S supports the following MMC messages.
■ Switching MMC reception on/off
You can specify whether or not the MD4S will receive MMC.
1. Press the UTILITY button, rotate the DATA dial to make the display read
“MMC Receive,” and press the ENTER button.
The display will indicate the current MMC reception setting. With the factory settings this is
off, and the display will indicate “MMC Rx OFF.”
2. Rotate the DATA dial to switch the setting “ON” or “OFF.”
When this is “ON,” MMC can be received.
3. Press the ENTER button to confirm the setting.
