11. 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.
12. SYSTEM RESET (FF)
Reception
When this message is received, MIDI communications will be cleared, e.g.,
by clearing the Running Status.
13. SYSTEM EXCLUSIVE MESSAGE (F0)
13.1 MIDI TIME CODE (FULL MESSAGE)
The Automix synchronizes these messages when they are received at a port
specified by the TIME REFERENCE setting.
13.2 MIDI MACHINE CONTROL (MMC)
These messages are transmitted when the Machine Control section of the
02R96 is operated.
13.3 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.
CHECK SUM = (-sum)&0x7F
The 02R96 can transmit and receive BULK data only if the size of a MIDI
packet (F0 - F7) is 4096 bytes or smaller.
If large data consists of multiple MIDI packets, they can be transferred se-
quentially.
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
[MIDI]-[BULK DUMP] screen.
A bulk dump is transmitted on the [Rx CH] in response to a bulk dump
request.
The data area is handled by converting seven words of 8-bit data into eight
words of 7-bit data.
Conversion from actual data into bulk data
d[0~6]: actual data
b[0~7]: bulk data
b[0] = 0;
for( I=0; I<7; I++){
if( d[I]&0x80){
b[0] |= 1<<(6-I);
}
b[I+1] = d[I]&0x7F;
}
Restoration from bulk data into actual data
d[0~6]: actual data
b[0~7]: bulk data
for( I=0; I<7; I++){
b[0] <<= 1;
d[I] = b[I+1]+(0x80&b[0]);
}
13.3.1 Scene memory bulk dump format
(compressed data)
The 02R96 can transmit and receive scene memories in compressed form.
13.3.2 Scene memory bulk dump request format
(compressed data)
The second and third bytes of the DATA NAME indicate the scene num-
ber that is being requested. If this is 256, the data of the Edit Buffer will be
bulk-dumped. If this is 8192, the data of the Undo Buffer will be
bulk-dumped.
