Genuine Yamaha "C/F" key for "FS type synthesizer action. Also fits many Korg models.

Pulled from a Yamaha DX-5. Semi-weighted; with key spring included. (Some sellers charge extra for the key spring.) The "FS" action was Yamaha's highest quality synth action for decades until replaced in 2007 by the "FSX" action, starting with the Motif XS and on to the present day Montage.

This key will fit many Yamaha models including DX5, DX7, DX7S. DX7 II, DX7 IIFD, EX5, (not EX7), SY77, SY85, SY99, Motif 6, Motif 7, Motif ES6 and Motif ES7.

These will also fit Korg 01W, 01W FD, 01W Pro, i2, i3, i30, M1, OASYS 76, Trinity, Trinity Pro, Triton, Triton Extreme, Triton Studio, Wavestation, and Z1.

There may be other models that this key will fit, but of the models listed above I am sure.

Please be certain that this key will fit your instrument before ordering!   USPS shipping is included in the listed price and I can not be responsible for refunds to buyers who do not know what they are ordering. If you need a "C" key or an "F" key (the same key works for either note) for your synth, and you are sure that this is the style that you need, don't hesitate--if you delay it might be gone by the time you decide.
