Moog Music Subharmonicon

Moog Subharmonicon

Moog Subharmonicon is a semi-modular polyrhythmic analog synthesizer with a 6-tone sound engine and a multi-layered clock generator, built around subharmonics and polyrhythms. Two analog VCOs and four subharmonic oscillators, each derived mathematically from one of the main VCOs, produce coherent chord shapes; onboard quantization offers equal temperament, just intonation or no quantization.

Two 4-step sequencers animate the chords, each clocked by any of four rhythm generators that divide the master tempo by an integer. Dual envelopes, a Moog Ladder filter and an analog VCA shape the sound. The 32-point 3.5 mm patchbay connects to Mother-32, DFAM and other Eurorack gear (MIDI Type A adapter included). Subharmonicon works standalone with the included 12 V DC power supply or, with the front panel removed, inside a Eurorack system. It is inspired by Joseph Schillinger's system and by the Mixtur-Trautonium and the Rhythmicon.
