Can a MIDI Song Control Voice On/Off?

[Michael Trigoboff]

I just checked through the Genos Data List PDF, and didn't see anything that would allow a MIDI song to control which of the four voices (Left, Right1, Right2, Right3) are turned on/off. Is such a thing possible?

Hello Michael,

Suggestion:
In the midi file you could set the volumes
to "0" at the desired times.
Possibly via MixMaster.

If you mean the keyboard Voices you play with,
you can set this by inserting "Keyboard Voice"
when storing the midi file.
Midi Multi Recording > Set Up > check "Keyboard Voice"
execute > save.
This command stores the voices (L+R1+R2+R3)
and their settings in the midi file.
You can apply as often as needed.
Easiest is to first select all you want
save settings under the registrations
and load it whenever necessary
to commit the midi file via "Set Up" + "Execute".
If everything is to your liking : "Save"

Hi Michael --

Yamaha's mid- to upper-level arrangers support many undocumented Sy*** commands. Dromeus has made a few lists based on his discoveries:

You might want to give this Sy*** message a try:

F0 43 73 01 50 08 cc 00 dd F7    Part On/Off
cc =
   00H: Right1
   01H: Right2
   02H: Right3
   03H: Left
dd =
   00H: OFF
   7FH: ON

Hope this helps. It would be good to know if it works on Genos as well as Tyros.

Take care -- pj

When I made a cover of a song, I found the correct sy*** sequence for all kind of actions by doing the following:

• Press Record on my computer's MIDI sequencer
• Do the action on the keyboard, like Fill B, or press a voice button
• Stop the MIDI recording and look for the Sy*** parts

In this way, I made very short MIDI clips, containing only one command. I had a chord track, and a separate track for triggering fills and style variations. It is very flexible.

Maybe you can use this method to find the correct Sy*** messages for turning the voices on and off? You will probably find the same Sy*** commands as PJ describes.
