For a long time I have had problems with the default pianovoice at startup, there was a kind of vibrator on, like the MOD. wheel was a little on. Very annoying. To get it off I had to pick another preset voice and then go back to the piano preset again, then it was OK. It was the same at every startup. For the first time I have done editing to a factory preset voice.(not program) Except from renaming a voice that had the name changed when saving a voicelist. Had to go into MOD/WHA and set it to OFF. Now the voice is fine but the MOD wheel if OFF, but I don't use modulation wheel on the Piano voice anyway. Just thought I should share.
