I'm hoping someone knows a quick fix for a Roland keyboard I am working on. I replaced all of the soft microswitches under each key. Played it last night and moved it back to the owner tonight. Plugged it in and only the bottom half of the keyboard works. After playing around with it only about every 8th note on the soft switches works. Going back tomorrow to remove the switches and clean off circuit boards, check wires etc.
This thing is driving me nuts !!!!Its an older Roland 500 or something like that.
