    Thank you so much for sharing this, very informative. I have an RS09 with 1 dead key, and I am curious if you could point me in the direction of what component(s) to check. I am assuming the master osc. and both divider chips are working fine since all the other keys sound… Any tips would be appreciated!

      If its just one key check the keybed. Lift the faulty key out and check the plunger is far enough down. Compare with another key that works. This can be done my opening the front panel and releasing the spring on the back of the key.

    Hi, thanks for this really interesting. I’ve just picked up a Mk1 cosmetically and functionally I’m somewhat better shape, and generally looks more as though will need a good clean and some deoxit, the sale mentioned some crackle but I doesn’t seem to be caps, and as I have little to no knowledge in that arena I’ll leave it that way. However before I strip apart are there keyboard bushings as it feels very hard as though they’ve gone, I have replaced in some keyboards, but wanted to check and if so I’ll have so source some, kind regards Paul

      Hi Paul, the old Rolands use a plastic plunger that hits the wire contacts, so there are no rubber bushings to wear out or to act as a cushion. So its a harder feel, and the plungers can get pushed up into the key and need pulling down. Good luck with the restore! Rob
