yes, i meant the parameter button. so if i go on what you're saying then all three switches dont work. has anyone ever swapped these switches or cleaned/repaired them? i opened up the synth and tried to take them out. i couldnt get the caps off of them, i was afraid i would break them. any advice?

i just got a korg poly-61. three buttons dont work: the edit button, and the up and down button for editing. i figured i can just replace the switches, but because all three of these buttons are very related and needed for editing parameters, i'm curious if the problem isnt the switches. or maybe it...
