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 Specifications Rhythm: Derived by dividing the tempo by an integer value (1-16) Clock: 20 to 3000 BPM (1 pulse per quarter-note), MIDI Clock, Ext Clock Vcf Eg: Voltage-controlled decay and selectable fast/med/slow attack times VCA Eg: Voltage-controlled decay and selectable fast/med/slow attack times 17 patchbay inputs 15 patchbay outputs Sound Engine: 100% Analog Sources: VCO 1, SUB 1, SUB 2 / VCO 2, SUB 1, SUB 2 Filter: Self-Oscillating Ladder Filter, Low-Pass, 4-Pole (24 dB/Octave) Envelopes: VCA EG (Attack, Decay); VCF EG (Attack, Decay) Sequencer: 2 x Analog Sequencers Steps: 4 Steps per Sequencer, Selectable Quantization Clock: Driven by Any and All of the Rhythm Generators Rhythm Function: 4 x Rhythm Generators Rhythm: Derived by Dividing the Tempo by an Integer Value (1-16) Clock: 20 to 3000 BPM (1 Pulse per Quarter-Note), MIDI Clock, Ext Clock MIDI: Clock, Ext Clock Patchbay: Jacks: 32 x 1/8" / 3.5 mm Inputs: 17 Outputs: 15 MIDI: 1/8" / 3.5 mm MIDI Input (Type-A Dongle Included) Rear Panel: Headphone: 1/4" / 6.35 mm TRS Instrument Output: 1/4" / 6.35 mm TS Power Supply: 12 VDC Input Security: Kensington Lock Slot Power: Power Supply: 100 to 240 VAC; 50/60 Hz, +12 VDC, 1200 mA Power Consumption: 4.8 W Eurorack: 360 mA (Maximum) from +12 VDC (10-Pin Header) Dimensions: Enclosure: 12.6 x 4.2 x 5.2" / 32 x 10.7 x 13.3 cm (with Knobs) Module Depth: 1" / 2.5 cm Horizontal Pitch: 60 HP Weight: 6 lb / 2.7 kg
