Reception flow diagram
Note:
sw1: Reception channel in SETUP
sw2: When in RECORD, the SETUP velocity on/off
sw3: When in PLAY, this is "on" when the SETUP sync is set to
"MIDI"
sw4: The device number selected in utility (setup)
sw5: Received only when the utility setting memory protect is "off".
sw6: Received only when UTILITY (setup) midi sw = on
Transmission flow diagram
Note:
sw1: The transmit channel in SETUP.
sw2: The device number in utility (setup)
sw3: Transmitted only when UTILITY (setup) midi = on
Channel messages:
Transmitted only during PLAY and while recording. For the reception
and transmission conditions, see the reception flow diagram and the
transmission flow diagram.
Mode messages:
Neither received nor transmitted.
System common messages:
Only $F2 (song position pointer) is received (however not when in
recording mode nor during playback). Other messages are neither re-
ceived nor transmitted.
System Realtime Messages:
$F8. $FA, $FB, and $FC are transmitted and received. (However when
in recording mode, $FA, $FB, and $FC are not received.)
BULK DUMP:
Five types of bulk data are transmitted and received. The
transmission/reception channel can be set in synthesizer mode.
1. $F0 43 0n 7E bb bb LM_8073RY (r.seq data) F7
2. $F0 43 0n 7E 00 1A LM_8073RS (r system data) F7
3. $F0 43 0n 7E 01 41 LM_8073RI (r inst data) F7
4. $F0 43 0n 7E 00 47 LM_8073K0 (r kbd asgn1) F7
5. $F0 43 0n 7E 00 47 LM_8073K1 (r kbd asgn2) F7
Reception is possible at any time except while playing or recording.
Transmission occurs when MIDI exclusive "bulk dump" has been
executed, or when a dump request has been received.
For the data formats of system (SYSR), inst setup (RINST), and
kbd assign table (RKAT), see the data format table of the synthesizer
section (table 4).

(2.1) RHYTHM SEQUENCE
Note 1) data format
count size(byte)
0 - 217 218
218 - 317 100
318 - 417 100
418 - 481 64 (8x8song) song name
482 - 10239(max) 9758 (max)
The above data is divided into MSB4 bits and LSB 4 bits, and each
converted into an ASCII code. If the data count exceeds 4K bytes, the
data from "BYTE COUNT" to "CHECK SUM" is repeated for every
4K bytes.
