Drone Commander

With a total of 9 knobs, the Drone Commander offers two manually-tuned oscillators and two LFOs, plus an unusually colorful and nasty filter. LFO1 is an analog variable-shape oscillator, and LFO2 is a pulse waveform that auto-synchronizes to LFO1 at a ratio of 2x, 4x, 8x, or 16x. Both LFOs can be routed to the filter for rhythmic patterns.  A line-level output jack is provided for connection to amplifiers or effects.

The sound samples on this page are recorded with one Drone Commander plugged straight into a Fender Princeton Chorus.

Six of the Drone Commander’s nine knobs double as push-pull switches to control signal routing and waveform selection. Scroll to the bottom of this page to view the control layout.

The Drone Commander is housed in a dark green military ammunition case with engraved aluminum control panel. The case is welded steel with an easily removable, rubber gasketed lid. There is almost no plastic in the drone commander! It measures 10″(w) x 7″(h) x 3.5″(d), and weighs about 6 lbs.The unit is powered by a 9V battery accessible through a slide-out drawer in the side, as well as a 9VDC adapter.

Filter CV input (0-10V) and clock pulse output (+8V) are now standard features.

“I was able to fire it up and dial in sounds for… what turned out to be a couple hours. So far I can say I’m very happy with it. The sound is rich and versatile, very musical–haven’t yet found a setting that sounds cheesy or doesn’t work. It complements my other gear perfectly. And the fact that it has a built-in case is genius–it feels very sturdy. Very cool aesthetic, wish there was more stuff like this. Definitely gonna be recording with it in the near future…” - Mike A, Seattle


“Beautiful construction/presentation in the housing and the sounds are ridiculous. The CV in to the filter is ruling. Gate outs are driving the step sequencer in the Dave Smith Evolver with no problem. sick sick sick!” - Tonewrecker
