Moog Subharmonicon is a semi-modular polyrhythmic analog synthesizer designed for exploring sequences that unfold and evolve over time, spiraling through 6-tone subharmonic chords and organic polyrhythms.

The unique approach of Subharmonicon to music creation is inspired by the innovative ideas about electronic instruments and experimental music that emerged during the 1930s and 1940s. Combining music and mathematics, these early avant-garde concepts laid the foundation for our modern exploratory practices. (For further learning, research the work of Joseph Schillinger, Oskar Sala, and Leon Theremin.)

The Subharmonicon is capable of creating complex sounds and patterns, yet it is incredibly simple to use. It features 2x VCOs, 4x subharmonic oscillators, 2x 4-step sequencers, and 4 rhythm generators.

The distinctive sound of Subharmonicon begins with two analog VCOs and four subharmonic oscillators, for a total of six powerful sound sources. Each subharmonic tone is mathematically derived from one of the two main VCOs, giving the resulting chord shapes a beautifully coherent quality. Built-in quantization allows you to snap to perfect intervals with selections for multiple tuning systems. Choose between contemporary equal temperament settings, the celestial intervals of Just Intonation, or the unlimited freedom of no quantization at all.

The animation of Subharmonicon's distinctive chord shapes is achieved through a polyrhythmic pair of 4-step sequencers. Each sequencer is clocked by any or all four Rhythm Generators, which produce mathematical subdivisions of the master tempo. Stack multiple Rhythm Generators to create complex polyrhythms and discover new, inspiring patterns and styles. Delve into Subharmonicon's dual envelope generators, the Moog Ladder Filter, and the analog VCA to bring out dynamic articulations ranging from lush pads to percussive and ritual rhythms.

Although no patching is required to start creating, exploring the Subharmonicon modular patchbay unlocks infinite worlds of possibilities as you make new connections and connect to new ideas. The 32-point 3.5 mm patchbay can be patched into itself, expanding Subharmonicon's capabilities, or interfaced with Mother-32, DFAM, and other Eurorack-compatible external equipment (a Type A MIDI-to-3.5 mm DIN MIDI input adapter is included). Use it as a standalone synthesizer with the included +12V DC power supply, or simply remove the front panel to install it in any Eurorack system.

The Moog Subharmonicon is a versatile analog labyrinth of subharmonic derived synthesis and polyrhythmic sound.
