Back in the 1970s, this synth started life as a custom design by a Buffalo engineer before Moog brought it into their fold, giving it a distinct look and sound that sets it apart from the classic Minimoog crowd.
At its heart are two analog VCOs pumping out sawtooth, triangle, and pulse waves with coarse and fine tuning, octave switching, and flexible modulation from dual VC LFOs—each with four waveforms, independent rate sliders, and an X/Y mix knob for blending them seamlessly. A single contour generator handles envelope duties with attack, decay, and sustain options, feeding into a self-oscillating 24dB/octave ladder filter that's keyboard-trackable for soaring leads, plus a VCA for amplitude shaping. The source mixer blends osc A/B balance, ring modulator (using osc B or ext input as carrier), pink/white noise, and external audio in, all routed through duophonic play via a 49-key synth-action keyboard (C to C) with portamento, pitch bend, and CV/gate ins for osc, filter, and VCA. Housed in a portable blue suitcase with built-in speaker, headphone out, and monitor switches, its big tactile knobs and straightforward panel invite endless tweaking for basses, textures, and experimental weirdness.
Players dig its raw Moog tone and hidden depths—like LFO contour modulation and microtonal scaling on osc B—for everything from spacey drones to Freddy Fresh-style beats, though some note the single envelope keeps it from full polyphony dreams. A durable home studio gem that's as fun to explore today as it was back then.
