The Drone Machine is a drone voice consisting of three tunable 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 knob settings.
The modules output is not AC coupled so you are free to use it as a modulation source also. A volume control is provided to trim the output level to desired strength.
