Description

FOUR is a 4 oscillator squarewave desktop drone synth/modulation box.

The 4 oscillators are paired together and each pair is fed through a NOR logic gate before being routed to the output. The outputs of the logic gates can then be mixed together to create stacked drones and chords. FOUR can also be used as a CV source to control and modulate other equipment.

FOUR is powered by a 9V center-positive power supply (not included) or, alternatively, by a 9-volt battery block. A battery connector is included. PSU should be minimum 1A.

DO NOT USE A CENTER NEGATIVE WALLWART AS THIS WILL DAMAGE THE SYNTH.
