If [TABLE] is selected
If [NRPN] is selected
*1) There is no particular need to add the 2nd, 3rd, and 4th status
for transmission. However if these are present during recep-
tion, they should be received.
*2) Does not need to be transmitted if the parameter data fits
within 7 bits.
4. PROGRAM CHANGE (Cn)
Reception
This message is received if [Program Change RX] is ON and [Rx CH]
matches. However if [OMNI] is ON, this is received regardless of the chan-
nel.
A scene memory will be recalled according to the settings of the [Program
Change Table].
This message will be echoed if [Program Change ECHO] is ON.
Transmission
If [Program Change TX] is ON, this message is transmitted according to
the settings of the [Program Change Table] on the [Tx CH] channel when
a scene memory is recalled.
If the recalled scene has been assigned to more than one program number,
the lowest-numbered program number will be transmitted. Transmission
to Studio Manager using Program Change messages will not be performed
since there is no guarantee that the contents of the tables will match. (Pa-
rameter Changes will always be used.)
5. SONG POSITION POINTER (F2)
Reception
If this is received when the automix TIME REFERENCE setting is MIDI
CLOCK, the automix will move to the song position that was received.
6. TIMING CLOCK (F8)
Reception
If the automix TIME REFERENCE setting is MIDI CLOCK, this message
is used to synchronize automix. It is also used to control effects. This mes-
sage is transmitted 24 times per quarter note.
7. START (FA)
Reception
This message is received if the automix TIME REFERENCE setting is MIDI
CLOCK, and will start the automix. In actuality, automix will start when
the next TIMING CLOCK is received after receiving the START message.
8. CONTINUE (FB)
Reception
This message is received if the automix TIME REFERENCE setting is MIDI
CLOCK, and will cause automix to start from the current song position. In
actuality, automix will start when the next TIMING CLOCK is received af-
ter receiving the CONTINUE message.
9. STOP (FC)
Reception
This message is received if the automix TIME REFERENCE setting is MIDI
CLOCK, and will cause automix to stop.
10. ACTIVE SENSING (FE)
Reception
Once this message has been received, the failure to receive any message for
an interval of 400 ms or longer will cause MIDI transmission to be initial-
ized, such as by clearing the Running Status.
11. SYSTEM RESET (FF)
Reception
When this message is received, MIDI communications will be cleared, e.g.,
by clearing the Running Status.
12. SYSTEM EXCLUSIVE MESSAGE (F0)
12.1 MIDI MACHINE CONTROL (MMC)
These messages are transmitted when the Machine Control section of the
02R96 is operated. For details, refer to the MMC specification.
12.2 BULK DUMP
This message sends or receives the contents of various memories stored
within the 02R96.
The basic format is as follows.
For DUMP DATA
For DUMP REQUEST
A unique header (Model ID) is used to determine whether the device is a
02R96.
CHECK SUM is obtained by adding the bytes that follow BYTE COUNT
(LOW) and end before CHECK SUM, taking the binary compliment of
this sum, and then setting bit 7 to 0.
Reception
This message is received if [Bulk RX] is ON and the [Rx CH] matches the
device number included in the SUB STATUS.
When a bulk dump is received, it is immediately written into the specified
memory.
When a bulk dump request is received, a bulk dump is immediately trans-
mitted.
Transmission
This message is transmitted on the [Tx CH] by key operations in the [MI-
DI]-[BULK DUMP] screen.
A bulk dump is transmitted on the [Rx CH] in response to a bulk dump
