devices :: ACTG - the analog controller to go

ACTG is an analog controller for any synth or other device accepting GATE/CV signals

It works simple and straightforward - when a button is pressed GATE signal (5V) is send from one of the outputs and a CV (0-5V set by a coresponding knob) is send from the other output.
When two ore more buttons are pressed the control volteges are mixed and a middle value is send thus providing more tone options.
