“Yamaha CS 60
Has a Fault in which 3 out of the 8 notes ( polyphony wise ) don’t trigger a sound on the vcf or vca, but still do on the vco. So it sounds like it cuts out every 6th 7th and 8th note. No matter what key you are playing on at the time,,, the keys are all mechanically good.
Reason i havn’t had it repaired is that it still plays well as a 5 note polyphonic synth ( rather than the full 8 ).
I just keep the three notes that dont sound, held down with something,usually a little paperweight on the bottom three notes of the keyboard. Then it plays seamlessly through the remaining five notes. I will be happy to show whoever wins how to do this.
I suppose if you wanted to get it repaired then a few hundred quid and you’d have a full 8 note polyphonic machine….
Also 3 of the slider plastic tops are not there as you will see in the pic ( top left of the panel , to the right of the memory flap ), still easy enough to move without them. Though easily replacable.
2 of the keys have small marks on them but not noticable when playing on them.
Anyway, Everything else on the synth is fully working, all knobs, sliders, buttons, memory, keys, no crackles or pops when moving any of the sliders etc…
It’s an amazing synth, i’ve used it in the house to record loads in the past, but i’ve had enough of the synthy type sounds…. i want a Fender Rhodes now instead ; )
It has the top part of the case as well, the black tolex on the top part has marks on it here and there, but isn’t ripped. The bottom ( underside of the synth ) is fine.” Link
