Did a search and read that z3ta+ 2 doesn't accept program change messages. Is this true? I want to change sounds (banks?) during my song instead of loading a new instance of z3ta+ 2 into a new track everytime I want a new bank (sound?). Thanks for any information on this.

I don't know if you can change whole banks on the fly, but you can switch between patches within a bank by inserting patch change messages.  If you need sounds from more than one bank, you can create a custom bank, and copy the sounds you want into it.  Save them under "User Content" and "User Category".  Then you should be able to change them as needed using patch change messages.

wr, thanks a lot. Will look into this as to what I can do with your advice.
