Building upon the success of the Mother 32 and DFAM semi-modular synthesizers, the Moog Subharmonicon is a Eurorack-compatible, semi-modular polyrhythmic analog synthesizer designed for the exploration of sequences that unfold and evolve over time, spiraling through 6-tone subharmonic chords and organic polyrhythms, making it well suited for producers and musicians working in the studio or performing onstage.

The sound engine is based on the music making approach developed during the 1930s and 1940s, where Joseph Schillinger's avant-algorithmic concepts use music and math to create complex sounds and patterns using an easy-to-use interface.

Two analog VCOs and four subharmonic oscillators are combined for a total of six powerful sound sources. Each subharmonic tone is mathematically derived from one of the two main VCOs, offering well-defined chord shapes with a beautifully coherent quality. The onboard quantization provides perfect intervals every time with selections for multiple tuning systems. Choose between contemporary equal temperament settings, intervals of just intonation, or the unlimited freedom of no quantization at all.

Features

• Semi-Modular: No patching required
• 100% Analog: Unbridled sonic flexibility for a lifetime of inspiration
• Inspired by Joseph Schillinger’s mathematical system for musical composition
• Mixtur-Trautonium-based synth engine, which employed a series of subharmonic oscillators to generate electronic undertones
• Rhythmicon (developed by Leon Theremin): Capable of sounding multiple harmonically related polyrhythm generators simultaneously
• Two Analog Sequencers Steps: 4 steps per sequencer, selectable quantization
• Clock: Driven by any and all of the rhythm generators
