Using MMC to control the AW4416
MMC (MIDI Machine Control) is a group of MIDI messages used to control the
transport of an audio recorder etc. from an external MIDI device. The AW4416
supports MMC transmission and reception. This means that an external MIDI
device can control AW4416 transport operations, locate operations, selection
and disabling of recording tracks, or conversely that the AW4416 can control
transport and other operations on another MMC-compatible device.
In this section we will explain how MMC can be used to control various opera-
tions of the AW4416 from an external MIDI sequencer while MTC is being used
to synchronize the AW4416 and MIDI sequencer.
1. Connect the AW4416’s MIDI IN connector to the MIDI OUT connector
of the MIDI sequencer, and connect the AW4416’s MTC OUT connector
to the MIDI IN connector of the MIDI sequencer.
In this case, the MIDI sequencer will be the MMC master (the device transmitting
MTC) and MTC slave, and the AW4416 will be the MMC slave (the device receiv-
ing MMC) and MTC master.
2. As described in “Using MTC to synchronize the AW4416 and a MIDI
sequencer” (→ P.238), make settings on both devices so that the
AW4416 and MIDI sequencer will run in synchronization.
3. Press the [MIDI] key, and then press the [F2] key.
