The Drone Machine is a drone voice consisting of three light controlled square-wave oscillators and a internal ring modulator mixing the oscillators together.
Many different textures and drones can be created – phasing, rhythmic and high frequency radio style sounds are also available at different optical settings.
Made primarily for the noisician, running the unit through various effects.
The modules output is not AC coupled so you are free to use it as a modulation source also. a full size potentiometer is provided to trim the output level to desired strength.
