This is based on the Maximal Drone and Minimal Drone. The main difference being this replaces knobs with faders. It has 4 oscillators each with a coarse and fine tune.

It is powered by an internal 9V battery or external 9V DC center-negative power supply. CV input via 1/8″ jack and audio output via 1/4″ jack.

This was built by request for Thaniel Lee of Humanhood Recordings.
