I can't seem to find anything in the search any more... I have an instance of a Z3ta synth audio and midi track inserted... is there a way to add just another midi track and tie it to a different Z3ta sound?  I tried it but if you change the channel/patch/bank it changes the original synth sound.  I prob will just add more synth tracks if it's not possible, but hoping to reduce the overhead.

Some synths are multi-timbral, z3ta+ is not one of the them. It is not possible to have zeta+ play more than one program at the same time. Add another instance.
