What you are saying is making some sense to me. Not sure where to check those things you mentioned. I had PT about 10 years ago. It was a different computer and sound card. My son built this computer for me so I'm not really sure what synth is being used. Before I just assigned an instrument to a channel and that's what I got on playback. The only thing I'm seeing in PT is CayoteWT as the default synth. The only thing I'm getting from PG Music is delete and reinstall which does nothing. I really don't know how to separate the different patches to the assigned channel. It seems to me that the program should do that automatically. Thanks for your help. Sorry for being so dense. I just thought it would be good to use to make some backing tracks for my single. Especially with having audio now to do backup vocals. If you have any further suggestions I'm all ears.
