Perfect replacement for bad keys on my Nord. These replace the rubber key contacts and worked perfectly to correct two problems I had with my Nord. One key was silent in piano mode and sample player mode but worked in organ mode. Another key triggered maximum velocity no matter how lightly played. Also in piano/sampler mode. Due to low price and hassle of opening up the keyboard, I replaced all 61 key rubber contacts and cleaned everything and the 6 year old Nord is as good as new!
not for M-Audio Oxygen 25

I know these work on some keyboards, but not on my M-Audio Oxygen 25 (3rdGen.). They are too short, the keys feel "flappy", and pushing the key down doesn't create electrical contact at all. Hmm, maybe if I raise the whole contact circuit board . . .

Excellent fit for M-audio KeyStationPro88 Replaced all bubble contacts and velocity range is better than cheap orange ones when new. Package arrived so quickly it beat the email confirmation !
Works best for the last/upper octave (13 notes)
