MIDI DATA FORMAT

1. Functions
1.1. Scene Change
The settings of the [MIDI PROGRAM CHANGE TABLE] specify
the scene that is recalled when a Program Change message is
received.
The settings of the [MIDI PROGRAM CHANGE TABLE] specify
the program number that is transmitted when a scene is recalled. If
more than one program number has been assigned to that scene
memory number, the lowest-numbered program number will be
transmitted.
1.2. MMC Control
These messages allow basic recorder operations such as STOP/
PLAY/REC/LOCATE.
If you select the MIDI SETUP menu item MMC MASTER, MMC
commands will be transmitted according to the operation of the
transport. If you select MMC SLAVE, the internal recorder will oper-
ate according to the received MMC commands.
1.3. Effect Control
Depending on the type of effect, note-on/off messages can be used
for control.
These settings are made for the parameters of each effect.
1.4. Pitch Fix Control
When the Pitch Fix mode is engaged, note-on/off messages can
be used to control pitches.
1.5. MIDI Clock transmission
If you set MIDI OUT to MIDI CLOCK, MIDI clock messages can be
transmitted during playback or recording.
In MIDI Clock transmission mode, Song Position Pointer and Start/
Stop/Continue commands will also be issued, and during playback
or recording, MIDI Clock will be transmitted according to the MIDI
Tempo Map.
1.6. MTC transmission (MTC Master)
If you set MIDI OUT to MTC, MTC can be transmitted during play-
back or recording.
1.7. MTC reception (MTC Slave)
If you set MTC MODE to SLAVE, the internal recorder will operate
in synchronization with MTC messages received from the MIDI IN
connector.
1.8. Realtime control of parameters
Control changes can be used to send/receive internal parameters
in realtime.
1.9. MIDI Remote
The faders, ON keys, and RTZ/FF/REW/STOP/PLAY/REC keys
can be used to control an external MIDI device.
In PRESET mode, operating the above controllers will transmit
MIDI data according to the preset settings of the AW2400.
In USER mode, operating the above controllers will transmit the
MIDI data that you specify.

and reception will occur without regard to the MIDI Tx Ch and MIDI
Rx Ch settings.
For modes 2 and 3, reception will occur without regard to MIDI
