Hi John,

As Noel has indicated you may have a sound patch, called a program change (PG). A program change tells MIDI what sound patch to use. If a PG is in your MIDI track it will always change the sound to the one selected in the PG.

So how do you get rid of the PG. You need to use a MIDI editor. In BiaB go to the notation mode and click on the track you want to inspect. You will see a box with the sound selected, see picture one, i.e bass. Right click on it and select the sound you want to here, see picture two, i.e. bright piano.

Good luck.
