microtonal keybd?

[M. Nail]

i want to build a microtonal keyboard that spits out cv's to my Yamaha
cs-15.  I'd actually like to build two, cheaply...  I've got a vague idea
about having a bunch of resistors in series which a key would short out,
but how do you work out the resistance?  and what can by used for keys
(I'm thinking something like the AKS touch-keypad or the Buchla/Serge
capacitance plate things?) besides ebony and ivory (or big chunks of
moving plastic)?
