1. Recognized data
Received messages are transmitted without change according to the "MIDI: MIDI IN->OUT" and "MIDI: USB IN->OUT" settings.
■Channel Voice Message
These messages are received if the "MIDI: Rx CHANNEL" setting matches the MIDI channel number of the incoming message.
●Control Change
○Bank Select
Status 2nd Byte 3rd Byte
BnH 00H mmH
BnH 20H 00H
n = MIDI Channel Number: 0H – FH (0 - 15) 0=ch.1 15=ch.16
mm = Bank Number (MSB) : 00H - 02H ( 0 - 2)
* After this unit starts up, it operates with 00H as the bank number until a bank select message is received.
○Control Change Number #1～#31 (MSB), #33 - #63 (LSB), #64～#95
Status 2nd Byte 3rd Byte
BnH ccH vvH
n = MIDI Channel Number: 0H – FH (0 - 15) 0=ch.1 15=ch.16
cc = Control Change Number: 01H - 1FH (MSB), 20H - 3FH (LSB), 40H - 5FH (1 - 31, 32 - 63, 64-95)
vv = Value : 00H - 7FH (0 - 127)
* Recognized if "MIDI CC IN" = ON.
* Recognized if the "Assign: SRC" setting is CC#1--#31 or CC#64--#95.
Target value = (parameter min) + ((((cc value) - (act range low)) * (parameter range)) / ((act range High) - (act range Low)))
* When a CC# matching the CC# that is specified as "MIDI: EFFECT SW," "MIDI: EFFECT A," "MIDI: EFFECT B," "MIDI: TIME CC," "MIDI: FEEDBACK CC," "MIDI: E.LEVEL CC,"
"MIDI: TONE CC," "MIDI: MOD DEPTH CC," "MIDI: CTL1 CC," "MIDI: CTL2 CC," "MIDI: EXP CC," "MIDI: LOOP ON/OFF," "MIDI: LOOP REC/DUB,"
"MIDI: LOOP PLAY," "MIDI: LOOP STOP," "MIDI: LOOP CLEAR" is received, that controller is controlled.
* LSB (#33 - #63) is received when "TIME CC" set to CC #1 - #31
CC #1 - #31
MSB value = 0
Parameter value = parameter min
MSB value = 127
Parameter value = parameter max
Others
Parameter value = (((cc MSB+LSB value) * (parameter range)) / 16383)
cc MSB+LSB value = (MSB value) * 128 + (LSB value)
CC #64 - #95
Parameter value = (((cc value) * (parameter range)) / 127)
* "FEEDBACK CC," "E.LEVEL CC," "TONE CC," "MOD DEPTH CC"
Parameter value = (((cc value) * (parameter range)) / 127)
Parameter range = (parameter max) - (parameter min)
●Program Change
Status 2nd Byte
CnH ppH
n = MIDI Channel Number : 0H - FH (0 - 15) 0 = ch.1, 15 = ch.16
pp = Program Number : 00H - 7FH (0 - 127)
* This message switches to the patch that is specified by "MIDI PC MAP."
■System Realtime Messages
●Timing Clock
Status
F8H
* Recognized if the "MIDI: SYNC" setting is other than INTERNAL.
