This is meant to be a description of my experiences concerning the „sticky keys“ problem with the Korg 01/W. See the excellent On-Line Guide to the 01/W by Ken Westover or join the 01/W mailing list to get more information on the 01/W. Maybe you want to listen to the 01/W factory demo while reading this stuff. Recorded it with the 01/W directly plugged into the AX-44 expansion unit of my Yamaha DSP-Factory.

Emmanuel KATZ sent me his french translation Réparation du symptôme des «touches collantes» du KORG 01/w of this article with the kind offer to provide it here for download, available either as zipped MS Word document (8.2 MB) or as PDF file (1.5 MB).
Besides owning and playing synths like Korg 01/W, Korg 707, Roland U-20 and E-MU Classic Keys, Emmanuel’s profession is being a project leader in development. Visit him at OSymbian.com.
Update (May 20, 2007):
Robert Viands posted a link to his website where he describes his experiences with fixing sticky keys on the 01/W without taking it completely apart. Check this out.
Update (August 03, 2008):
My 01/W suffered from a „no sound“ problem due to leaking electrolytic capacitors on the mainboard. See this article for a description of how this could be remedied.
Got the 01/W in 1992 as the winner of the monthly Keyboards Give-Away. Since then there were many hours playing the instrument on stage and at home. About four years ago some keys moved more and more sluggishly until they finally got stuck every now and then. Recently the battery went low and I decided to get rid of the problems by fixing them myself.
Unplugged the power cable and put the 01/W on a thick cloth to prevent damage on the panel. Removed the bottom plate and looked at tons of printed circuit boards. Decided to avoid static electricity and sat down to have a coffee and meditate.
The joystick panel shield. It had to be removed to get the keyboard out.

The aftertouch board and a closer look on the activator strip.

Lots of screws lying around well assorted for later reassembly.
Even more screws, and again assorted.
The keyboard after being removed without any hurts. Thought the fridge would be a nice background. Paid attention to the aftertouch strip.

The keyboard viewed from the left. Tried to come across the mechanism. Basically it all works without the grease. The key is hanging on a small plastic clamp on the bottom side. The action feeling is produced by the combination of a spring in the middle and a lead weight on the inner front.
It took some time, still tried. I have learned that it is not just the lubricant getting sticky which then causes problems but the lubricant combined with the dust & dirt getting stuck even worse then in the mechanism. After cleaning the keyboard it slightly worked without any grease as there is nothing in it to rub inherently. The lubricant does it’s job if you deeply strike the keyboard bending the keys to the left or right.
Meanwhile put the keyboard onto the table and removed the fixing strip.
Removed a key and meditated.
Removed some more keys and meditated.
Removed all keys and suddenly knew where all the dust and dirt had gone. Ken Westover writes: „Several users highly recommend completely removing the delicate activator strip before doing any work. This takes more time, but activators are easily damaged while working on the keys.“ Didn’t believe this and thus had to pay my bill: Later, while re-fixing the keys, there were three activators bent off. Thank god, they did not break and I had a fair chance to fix it. Of course, I had to remove the activator strip for this, so why not do it right now ?
Cleaned the keyboard and fussily removed the sticky old grease. Spent a long time looking for the right lubricant. Took an ivory key with grease on it and went to some electronic and modelling shops to hear what they would recommend. Actually Klüberpaste, which is also used for VCR or tape-deck repairs, made it. Did not try teflon-lubricants that may be the better choice in the long run (out of stock). Prepared 10ml of Klüberpaste in a shot.
The freshly greased keyboard. Needed only 2ml. Reassembled my 01/W and got lucky. It’s a bit like having a new one. New battery and one of the best keyboards one can have. Don’t know how long the lubricant will do it, but yet it works great.
PS: Still great in 2022 ;-)
These are a few photos of my Leslie 710. Took them in here for sentimental reasons, although the quality is poor due to the Philips Vesta PCV680 webcam that I had to use for shooting.
