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 :)

  David
