Thank you very much for the ideas! The Variation buttons did stop working simultaneously, and they are the only two of the 11 on the piano that are non-functioning. I can still use the piano as it is - just can't change from a grand to a honky-tonk piano sound for example. So you're right, Dave, it's probably a loose common connection. Not a major problem. *whew*

The kids I teach can be a bit heavy-handed in their enthusiasm as they explore those sound variations sometimes! GGRRRRRRR I'm 99% sure nothing was spilled on it, as I do keep the plastic cover over it when it's not in use.

I'll look for a can of compressed air, MMario, and for the aerosol HiHo Silver mentioned too. Off to trusty ole Canadian Tire, and Radio Shack then ... and thank you all again!
