Korg Poly800/EX800 Users

Hi. I was just checking if anybody knew about replacing (or maybe 
just cleaning) the progamming buttons. Some of mine are unreliable, so 
programming really sucks! I was also thinking that maybe it would be 
possible to remove the up & down value buttons, and replace with a 
fader, like poly800 and dw8000. I just got this from my friend for 
cheap, and was thinking of messing around with some mods, so if you 
know about some interesting projects I'd like to find out!

									Thanks
