I've just begun messing around with using these MIDI apps to interact with outboard devices (Yamaha keyboard, Boss drum machine, and Flextone guitar amp), but can't find a way to have a single track sequence contain multiple program change codes. Looking at program documentation and other MIDI information failed to turn up anything applicable, or called "insert program change" as I would expect. Master Track edit in MusE is also a mystery. Any advice on how to do this, or where to look for information? Thanks! Frank
