GuitarHacker and 57 Greg, Thanks very much for this info on setting up multiple sound center music instruments. I have it working now and this is great. Love the sound and quality of sound center instruments. I actually had your ideas emerge shortly after I wrote the post because my Magix Music Maker 2013 program is using the same approach of a different synth for each instrument. You both got me on the right course, thank you very much. I see now that the critical issue besides multiple synth set up is to set the output channel to the appropriate synth that has the appropriate instrument. Took me a while to get to that point also but I am off and running now, best regards, Clifford
