The loud pedal solenoid makes a lot of noise. Is there a easy way to reduce the voltage or regulate this solenoid? Do any of you have tech info as = far as the (I think pianodisk)player adjustments and regulation? I've corrected the warped keys and the completely erratic key leading and I'm now stalled with the electronics. Any help would be greatly appreciated.
