4. MIDI format details
4.1 NOTE OFF (8n)
< Reception >
Received if [Rx CH] matches.
Used to control effects. See below for details.
STATUS 1000nnnn 8n Note Off Message
DATA 0nnnnnnn nn Note No.
0vvvvvvv vv Velocity (ignored)
4.2 NOTE ON (9n)
< Reception >
Received if [Rx CH] matches.
Used to control effects. See below for details.
If velocity is 0x00, same as note-off.
STATUS 1001nnnn 9n Note On Message
DATA 0nnnnnnn nn Note No.
0vvvvvvv vv Velocity (1-127:On,
0:off)
* Notes used to control effects.
1: Dynamic Flange / Dynamic Phase / Dynamic Filter
If the SOURCE parameter is set to MIDI, velocity will con-
trol the width of frequency modulation for both note-on and
note-off.
4.3 CONTROL CHANGE (Bn)
< Reception >
Echoed if [Control Change ECHO] is on.
< Transmission >
If [Control Change ECHO] is on, this is merged with the
AW4416’s own output while taking advantage of running
status.
4.4 PROGRAM CHANGE (Cn)
< Reception >
Received if [Program Change RX] is on and [Rx CH]
matches. However if [OMNI] is on, this is received regard-
less of the channel.
This is echoed if [Program Change ECHO] is on.
A scene memory will be recalled according to the [Program
change table].
< Transmission >
If [Program Change TX] is on, a recall operation will cause a
program change to be transmitted on the [Tx CH] according
to the settings of the [Program change table].
If more than one program number is assigned to the mem-
ory number that was recalled, the lowest-numbered pro-
gram will be transmitted.
If [Program Change ECHO] is on, program changes will be
echoed.
(If a memory number is recalled for which there is no setting
in the [MIDI Program Change Assign Table], no program
change will be transmitted.)
STATUS 1100nnnn Cn Program Change
DATA 0nnnnnnn nn Program No. (0-127)
4.5 MIDI TIME CODE QUARTER FRAME (F1)
< Transmission >
When MTC transmission is selected and the recorder is in
PLAY or REC status, Quarter Frame messages will be trans-
mitted according to the time code operation of the recorder.
< Reception >
These messages are received if the AW4416 is operating as
a MTC slave. Quarter Frame messages received in realtime
are assembled internally to create time code values that
control the recorder.
