PSIM-1!

Using 1v/oct, the PSIM outputs have 32 voltage steps between half notes.
 (c=0, c#=32, d=64, etc)

By adjusting the voltage steps between notes, you can easily create
micro tuning scales, non western scales, etc.  The "spread" control of
the Buchla could be done quite easily.

I'm tellin' ya, this module is a wolf in sheep's clothing :)

David, you're coming close to what I'm thinking of.

The standard keyboard is a handy interface, but what if I don't want to
apply the usual chromatic arrangement to the patch I'm using on an
analogue modular (or anything else analogue which has a CV input)?  The
modular itself is calibrated for 1v/octave on the primary VCO CV inputs
(the Fenix, for instance).  Arguably, one could 'play' the frequency
knobs, but this may be a bit haphazard for all but the most precisely
coordinated of performers if one is using the gate signals for other
articulations.

What I'm thinking of is a controller that allows the user to determine
the pitch cents/ratio/semitones between each key.  
I *think* the KS part of the EMS Synthi AKS addressed this by employing
a little wheel labeled 'spread' and I believe that at least one of
Buchla's touchplate keyboards had two pots for each plate that one could
employ to similar ends.  Comparatively speaking, these schema are
'primitive' in view of what we have access to nowadays.  With all the
brainpower that's gone into software development in the last 30 years,
you'd think someone would have come up with a way to circumvent equal
temperment and make this option pretty commonplace.  Perhaps there are
limitations to design on either end of the equation that I'm not
educated on.  My interest in this is far more dictated by a desire to
(sometimes) be free of standard scales, rather actually having a deeper
understanding of alternate tuning systems on the level of, say, Robert
Rich.

So, yes, a MIDI keyboard that allows 'free quantization' between each
key...
