Bill,

You have to be in Fingered mode in order that holding down any three adjacent keys at the same time will play just the drums alone.
If you play 4 keys, the lowest will be a bass note along with the drums.

Holding down C6 at startup will reset, I'm not sure if this one also clears Registrations, but you have your Registrations saved on diskette, no ?

However, I do not think this will solve button problems.

John
