keyper Posted October 4, 2006 Share Posted October 4, 2006 I've got a Roland A30 with a bad key - it's waay louder than the others, almost like the velocity sensitivity is cranked - but for just this one key. I'm pretty sure it's a hardware issue because I rebooted set to factory defaults. I picked this old girl up real cheap so it doesn't 'owe' me anything per se but I'd sure like to restore it if I can. Anybody have any experience with these sort of things? Link to comment Share on other sites More sharing options...
Rhodes54 Posted October 4, 2006 Share Posted October 4, 2006 I've had this problem on numerous brands of keyboards. You have to take the keyboard out and clean the rubber contact underneath the offending key. It's a pain in the ass, but can be done easily enough. Best of luck!

keyper Posted October 4, 2006 Author Share Posted October 4, 2006 Any suggestions as to the type of cleaner? (thanks btw) Link to comment Share on other sites More sharing options...
Rhodes54 Posted October 4, 2006 Share Posted October 4, 2006 I'm NOT a tech, but I've always used a dab of 91% isopropyl alcohol (any drugstore will have it) on a Qtip and never had any problems until the next time some dumbass singer or guitarist spills a drink on it. I've had this problem/solution over the years on a Roland RD-250, Ensoniq SQ-2, Kurzweil PC88 and lately a Nord Electro. It's either the high velocity thing you describe or an intermittent connection and that's always the culprit. Link to comment Share on other sites More sharing options...
keyper Posted October 4, 2006 Author Share Posted October 4, 2006 Thanks! I'll give that a try. Link to comment Share on other sites More sharing options...
Ian Sharrock Posted October 4, 2006 Share Posted October 4, 2006 I've used distilled water on a Qtip, I'm never sure that the alcohol isn't stripping the carbon contact off the membrane. I've cleaned both FZ1s, and my Roland A33 key contacts with 100% success. Gig rig: Motif XF8,Roland A37~laptop,Prophet 08,Yam WX5~VL70m. Studio: V-Synth GT,Korg DW8000,A33,Blofeld,N1R,KS Rack,too many VSTs Freefall www.f-music.co.uk Link to comment Share on other sites More sharing options...
dementedchord Posted October 4, 2006 Share Posted October 4, 2006 yeah... a good contact cleaning in your future... BTW i am a tech and never use water or isopropyl... water can sometimes saturate the pad and the oils and such added to the alcohol is just as bad... go to a paint store and get the pure stuff... incedently something else i always did was take the offending keystrip and swap it with one from a low traffic area...

keyper Posted October 5, 2006 Author Share Posted October 5, 2006 Originally posted by delirium: only one bad key? try avoid bastard... Haarrr!! Thanks for the (Q)tips everyone. I've had similar problems trying to clean telephone keypads. Tried mild cleaners and uppity zero-residue sprays - no real solution. Now I buy cheap wireless phones because when they go I have no problem tossing them out. Hopefully the A30 will be easier. One more question: I've had the A30 apart and I'm wondering just how deep into the thing I have to dig to get at the offending part. Can anyone point me at the best angle of attack?

gangsu Posted October 5, 2006 Share Posted October 5, 2006 Hey, I just had my keyboard apart last weekend for the same issue - 2 offending keys. I used typical drug store isopropyl alcohol, but instead of Q-tips, used disposable eyeshadow applicators. They're high density foam, and there's no chance of leaving behind any fuzz. Depends how anal you wanna get I guess. It took 2 hours here, but neither myself nor my computer geek buddy had been inside a keyboard before. I expected to see actual crud on the contacts, but no. I couldn't imagine that the cleaning would make any difference - but voila, good as new! Good luck and patience, especially replacing the fragile strip of rubber bins that house the opposing contacts. (if all keyboards are similar..) "........!

gangsu Posted October 5, 2006 Share Posted October 5, 2006 I never thought to take a pic of the actual contacts, but you might expect to see something like this after you've removed the action and turned it over.
