MP-2
System exclusive specification v1.1
Bernard Escaillas - 2011
1 Conventions
Values appearing in this specification in bold black mono type face are shown in hexadecimal.
Byte values are displayed on 7bits (00 to 7F, then 0100 to 017F, etc...)
Examples: 02, 20, 0123
Note: as explained in section 3, third value of the example will be noted as 42 01 23.
Values appearing in standard font are the decimal representation.
Examples (same intrinsic values as in example above): 2, 32, 163
2 Message generic format
F0 SOX: Start Of eXclusive
0D ADA: Manufacturer ID
00 CHN: channel number 00-0F (correspond to value 1-16 as set in global settings)
?? MID: message id (see section 5)
?? DAT: zero or more 'data word' (see section 3)
...
?? CHK: checksum (see section 4)
F7 EOX: End Of eXclusive
3 Data format
Reading 'data word' format:
If value between 00 and 3F: direct data
If value = 41: data is the following byte
If value = 42: data is the two following bytes, MSB then LSB
If value = 7F: special case for program#, designate edit buffer
Writing 'data word' format:
If value between 00 and 3F: write data byte
If value between 40 and 7F: 41 then data byte
If value between 0100-7F7F: 42 then 7 bits MSB byte then 7 bits LSB byte
If value is edit buffer #: 7F
4 Checksum
The sum of all bytes including checksum between F0 and F7 (not included) should give a value where 7 lower bits are
zero. In other words, the equation is:
( ADA + CHN + mID + DAT1 + DAT2 + ... + checksum ) and 7F = 0
or
checksum= ( 80 - ( ( ADA + CHN + mID + DAT1 + DAT2 + ... ) and 7F ) ) and 7F
5 Message IDs
Table below gives layout example. The response part noted [ID] appears only if a response is expected.

Response example
01
Reset! Resets command (side effect: switches to user bank)
F0 0D 00 01 72 F7
02
Test! Runs diagnostic command
Test# Test number 00-03
F0 0D 00 02 01 70 F7
03
Result? Requests diagnostic result of the last ran test
F0 0D 00 03 70 F7
00 03
Result Diagnostic result
Code 00 = no error, > 00 = error code
F0 0D 00 00 03 42 01 00 2D F7 error 128
04
Channel! Changes Midi channel
Channel {00-0F}={channel 1-16}
F0 0D 00 04 01 6E F7 change from channel #1 to #2
00 04
Channel
Channel {00-0F}={channel 1-16}
F0 0D 00* 00 04 01 6E F7 set to channel 2.
(*) message header is formed with channel number before change…
05
Offline! Changes Midi channel to ‘Off’
F0 0D 00 05 6E F7 Note: channel must be set back manually because the MP-2 will
not be able to receive any further midi message…
06
Values! Set some parameter values for one program
Prog# { 00-3F, 4140-417F, 7F 7F }={ 1-64, 65-128, edit buffer }
Count Number of values { 01-42010C }={1-140}
Address Address of first value { 00-42010B }={0-139}
F0 0D 00 06 00 02 00 30 31 0A F7
change two first letters of program name with characters '0' and '1'.
00 06
Result
Code 0=no error, >0=error code
F0 0D 00 00 06 00 6D F7 no error
07

Address Address of first value { 00-42010B }={0-139}
F0 0D 00 07 00 01 00 6B F7
program #1, 1 value starting at address 0 (first letter of program #1 name).
00 07

Count time Data word
F0 0D 00 00 07 00 01 20 4B F7 : first letter is a space
08

Format { 03 }={ ? }
Prog# { 00-3F, 4140-417F, 7F }={ 1-64, 65-128, edit buffer }
F0 0D 00 08 03 41 7F 28 F7 : request prog #128
F0 0D 00 08 03 7F 69 F7 : request edit buffer
09

Format { 03 }={ ? }
Prog# { 00-3F, 4140-417F, 7F }={ 1-64, 65-128, edit buffer }
Data 140 data words (see map in section 6)
0A
All? Request all data (note: response is message ID 0B)
Format { 03 }={ ? }
F0 0D 00 0A 03 66 F7
0B
All! Send all data (same message both ways)
Format { 03 }={ ? }
Map 128 words for program change table (map)
? ? words
CC# Tuning mute controller # { 00-3F, 4140-417F }={ 1-127 }

128 time 140 data words (see map in section 6)
Note: MP-2 replies to Program request (08) with program # above 128 (like 420100) but I don’t know what kind of data it
is. Does not look like preset data… what else? Firmware data? Garbage?
