Undertones and polyrhythm
A playable Moog Subharmonicon, measured off the real panel. It is built on two ideas, both of them division: each oscillator's SUBs are its frequency divided by 1 to 16, and each RHYTHM divides one tempo clock by 1 to 16. The lessons below take them one at a time, then put them together; the patch library at the bottom is the shelf of things to play.
Drag knobs up and down (shift for fine). Click the rubber buttons to light them. EG: click for on or off, press and hold for held (a drone). To patch, click a boxed output then an input; click a plugged jack to pull its cable. Readouts show clock positions and what they mean (÷3, a note name, a time).

The six voices
Tune your Subharmonicon to this patch
Plug the Subharmonicon's output into your interface. Pick a voice, set the hardware up the way it says, and turn the knob until the needle sits in the middle. The lab's own sound pauses while you tune, so it only hears the hardware.
Patch sheet
Save what you make, or copy it out as clock positions to set your own Subharmonicon the same way.
MIDI
Choose your MIDI in from the device bar at the top. Notes play both oscillators (with QUANTIZE applied), like the Subharmonicon's own MIDI input.
The lab
Chord library
Divider combinations worth knowing, held as drones. Load one, then tune your hardware to it with the card on the left.
Patch library
Things to play, beyond the lessons and the still chords: moving drones, sequences, polyrhythm, basses, percussion and cable tricks. Each is a full panel plus at most two cables, so you can set it up on your own Subharmonicon.
