Another step that I am having issues with. Are the Biab instruments pre assigned to the Roland program channels If I try to replace the instruments by selection of an alternate. They keep resetting on odd instruments. I'm thinking that the original Biab file is programed to work with the Sound canvas GM1 format. Could that be why I am unable to make instrument changes. Is there a switch to turn off the GM compatibility so I can use my own instruments(vst)
