wesen’s MNM minicommand firmware had similar features (reload kit)and in general the way that worked was:

  • when the minicommand is powered on, it queries the MNM via sysex and stores all of the kit / machine data etc in its own internal memory

  • when the “reload kit” button is pressed then the minicommand just sends all of the kit / machine data etc back to the MNM via sysex

for the CTRL-AL, from memory i think you just need to know what midi channels the monomachine is using (on the minicommand this was done at powerup as per above), then send a midi CC for what ever param you want to CTRL-ALL across all of the midi channels that are being used.
