I think that's the problem. The keyboard is a 1994 Solton MS 60. Dug it out this week-end to use the drums for a project. Noticed the programs I created don't work. Think it's a battery. Questions are: Is this thing worth repairing (I played it 4 nights a week for 20 years). Is this an easy repair for a general electronics shop? Over the years, I've had people tell me this ancient thing is sought by players of Portuguese music...is that right? How much are they worth?

I haven't used it as an arranger for years, but really like some of the drums for film work.

HELP!
