Has anybody else experienced that? I'm using two programs, Synthesia and Notation Composer. I tried to hook up to MIDI Illustrator Maestro, it didn't happen there though. In the other two programs, the tone is always changed to GM Piano 1. Is there any way to prevent this from happening? This almost makes it impossible to hook up to the named software packages. I tried changing the Local Control when connecting the Synthesia, after consulting with the Synthesia developer on the software's webpage. It worked better but the volume was much lower that way, probably because the external software was in charge of the piano. Not sure about this though. With Notation Composer, setting Local Contral to Off didn't change a thing. The software kept switching my PX-5S to the annoying GM Piano 1.
