I may have gotten something wrong, Mac. But the patch on a channel can be set to a guitar, for example, especially at the beginning of a file. But there is a bank change or incomplete bank change that is in the file. If the TTS does not recognize the bank change, when the track begins to play TTS will sound the notes in, usually, a piano sound, if that is the default instrument for that channel in TTS. I hope that is what I said in the earlier post. Ha!

So, I realize that patch and bank are two different things and tried to describe as best I could what happens.

Thanks, Scott
