Does any body built some to control their tube synths???
I'd like to build a joystick for cv/gate controlling...
and did any one tried the Judd auto bellgate and controlled bell gate???

most of the 'modern' tubesynths built so far have been designed to
work with regular analogue synth signals. I put a joystick on mine but
it controlled the CGS tube and Schmitz neon VCOs via the solid state
inputs.

it would be easy enough to hook up the pots on a joystick to control
the   frequency of an an all tube oscillator.

not yet but they are on my (ridiculously long) shortlist
