Modular Synth Panels

I have this really cool EML 301 controller that has a joystick, filter
and a pitch knob matrix (that does other stuff)

http://www.sequencer.de/pix/eml/eml-400.jpg

The really cool part is: There is a matrix of 12 knobs on the panel,
each knob is triggered by a telephone/calculator type membrane keypad.
You set the pitch and press the number and get a fixed pitch output. I
would suppose it could also be output of various types, cv, selected
waveforms.  A set and forget control for a modular.

I am thinking this would make a nice composing and performance module.
 I can't copy the EML circuitry because it is not to a modern
standard, weird scale and 1st gen op amps.

Any help available, any interest ?

So, of the 16 steps, are they arranged so that each switch always gives 
a higher voltage than the previous switch?
If so, then you could use cgs.synth.net/modules/cgs10_pedal.html

I was thinking of something far simpler. Keypad - fixed voltage amazing in 1972.

Ken reminded me that my idea was pretty basic and that much more tricked out useful  
version (ie automated) is CGS59 B plus 12a s would do all I wanted, basically give the 
equvalent of a Serge 16x16 programmer/sequencer without touch pads. This is something 
enormously powerful compared to a keypad triggering a single voltage.   I would guess a 
practical version of this would be a an 8x8 (1 59 b basic package plus 4 a boards).  So it 
looks like I'm onto a version of the programmer sequencer.  With the proper panel it is an 
easy build and I can add a port for a keypad of other performance controller if I don't want 
to walk over to my 301.
