No , in my studio , my DSI prophet 08 respond perfectly to the octatrack bank change sending !
But to use CC for changing , now I know the procedure :
The forst thing to remember is that you have FIRST to send a midi bank chane and AFTER send a PRG change . Otherwise , if bankchang andprgchang are sent at the same time , it will not work.
So , all you have to do is sending a CC0 with a value of 0 and a CC32 with of value of the corresponding number of bank you want to send; Then you send a program change .
You are obliged to send a prg change if you want to see your synth changing bank , and I have also noticed that this prg chang has to be different.
hope it helps
