If ever you desire to place the reface CP on a different MIDI Transmit channel, you can change it with the following MIDI Parameter Change (System Exclusive) message:

F0 43 10 7F 1C 04 00 00 00 dd F7

F0 _ is start of Exclusive message
43 _ is Yamaha manufacturer ID
10 _ is Parameter Change, first Device
7F 1C 04 _ is reface CP product ID
00 00 00 _ is High_Mid_Low Address of System parameter: Transmit Channel
"dd" _ is the DATA BYTE 00-0F (is a channel 01-16)
F7 _ is end of Exclusive message

To figure value of the Data Byte "dd":
00 = channel 1
01 = channel 2
02 = channel 3
03 = channel 4
04 = channel 5
05 = channel 6
06 = channel 7
07 = channel 8
08 = channel 9
09 = channel 10
0A = channel 11
0B = channel 12
0C = channel 13
0D = channel 14
0E = channel 15
0F = channel 16

Examples:
F0 43 10 7F 1C 04 00 00 00 01 F7 = sets the reface CP to Transit Channel 2

F0 43 10 7F 1C 04 00 00 00 0F F7 = set the reface CP to Transmit Channel 16

SUper! Thanks! But what if my sequencer (Akai MPC 1000) have only 10 bytes (fields) to enter? And here we have 11(

Not sure, I’d try leaving out F0 - Start of Exclusive... if the area where you are entering is reserved for Sysex it might automatically insert that...but you should contact AKAI.

thanks! I'll try smth.

And how to send command to switch Local Control to off?
It should be smth like
F0 43 10 7F 1C 04 00 00 06 00 F7

Exactly!
