[sdiy] Building an expression pedal for MS20

[Jean Bender]

Hi !
Well, for a musical project, i need to control some parameters from
the MS20 with an external processor, and that's would be really great
if it could be controlled by foot.. In order to play with the cv
inputs cutoff. It should really do the same as when you are manually
turning a pot..
A bit like the mod wheel, but for the foot..  An expression pedal like
should be great, but i would have to build in a lfo ? Or a vco ?
Would somebody have advices, ideas.. Maybe this kind of project already exist..

Thanks for you repplies
Jean
