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.jpgThe 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 ?
