Yamaha CS80

So I have kinda given up ever finding a CS80 for a reasonable price but I do have a couple CS60s. It occurs to me that if the CS60 could be modded so that you could layer 4-voices assigned to the main panel with the other 4-voices assigned to the mini control panel you would kinda have a mini-CS80 (minus the polyAT keyboard of course). Anyone ever gone down this road and looked into it?

Hi Doug.

That was sort-of my idea back in 1981! I had just started college and
was a huge CS80 fan and got to play with a new one at a local music
store. I knew there was zero chance of affording even a used one so I
saved up for a summer and bought a used CS60 for $1000. My plan was to
get a second one and play them from one keyboard. It actually wouldn't
be that insanely complicated to take the the KAS board outputs from one
and have it drive the disconnected KAS outputs of the 2nd CS60.

What you're describing would be trickier - although much smaller and
lighter! It's easy to set the KAS chip to only scan 4 notes - that's
what it does in the CS50. Then you'd have to connect the triggers of
the 2nd 4 voices in parallel with the first 4 and lots of other, similar
wiring of control voltages. I guess the really ugly part would be on
the T boards which mix all the control voltages. You'd have to break
apart all the connections for the 2nd 4 voice cards to do what you wrote
to send the panel sliders to the 1st 4 and the memory sliders to the
others.

Now that I've either lost the non-technical folks or made the techies
very ill thinking about this mod, I'll just wish you good luck and look
forward to you selling the parted-out board of what's left of your
keyboard in a few months :)

I know I´m sounding like the proverbial old coot here, but why on earth would you want to slaughter a functioning CS60 just to get something which isn´t even a half-way house on the way to a CS80? CS60s (and 50s) are becoming more and more difficult to find as working instruments in their own right so why rip them apart unless a CS80 is in dire need of a transplant?

Keep it the way it is, I say...

Well I wanted to make MY CS60 into a dual-osc design which would be a lot more interesting TO ME. I think the people you should be worried about is like the guy who dismantled a "perfectly working" CS60 to sell it off as parts. That's not at all what I'm doing. I'm taking synth and making it more useful and desirable and hence less likely to be parted out in the future.
