Back in 2015, this synth kicked off Moog's dive into semi-modular territory, blending their legendary analog warmth with Eurorack compatibility in a compact package that's perfect for sparking ideas anywhere.
Housed in a rugged extruded aluminum panel with handsome wood side cheeks, it measures about 12.6 by 4.2 inches and weighs just 3.5 pounds, making it a tabletop staple or easy Eurorack fit at 60HP. At its heart sits a single classic Moog VCO pumping out sawtooth and pulse waves—pulse with adjustable width—spanning 8Hz to 8kHz (up to 16kHz with modulation), plus white noise and a mono external audio input. The sound routes through voltage-controlled mixers, a switchable low/high-pass ladder filter (20Hz-20kHz) with resonant bite, and a versatile AD/ASR envelope, all shaped by a wide-range LFO hitting audio rates with triangle and square outputs. Hands-on knobs, a 13-note single-octave keyboard with velocity and aftertouch, and a 32-point 3.5mm patchbay (five cables included) let you play normalized patches or go wild with custom routing, while the voltage-controlled 32-step sequencer stores 64 patterns with gate length, ties, glide, and accents—plus MIDI in-to-CV for gear integration.
Over the years, players love its raw, fat tones for everything from snarling leads to experimental FM weirdness, praising the intuitive workflow and build quality that invites endless tweaking without overwhelming beginners. Some note the single osc limits polyphonic density, but that's part of its focused charm as a voice in bigger rigs.
