The Yamaha AN1x Synthesizer mailing list

Ok, I'm finally ready to do it. Many of you know that I have been 
experiencing a misbehaving key on my AN1X. It sometimes does not send 
a note, and when it does it appears to send velocity = 127. Someone 
(suggested I open up the synth and look for dirt on the contacts. 

I am about to do so. Those of you who have opened up your synth, do 
you have any advice?

Best,

Jerry
