Back in 1975, this compact powerhouse introduced one of the earliest force-sensitive keyboards to a synth, letting you press harder on the 37 keys for real-time expression that felt alive under your fingers—perfect for those moments when you want to bend a note with pure touch.
Two analog VCOs with sync deliver thick, punchy tones you can mix via a dedicated control, feeding into a classic Moog ladder filter, VCA, and dual ADSR envelopes, all modulated by an LFO for sweeps and vibrato. A slide control panel offers fingertip tweaks to volume, plus touch buttons for synch sweep, glide, and octave shifts down 1-3 steps from its high-register default. Twelve presets—Mute, Trumpet, Oboe, Clarinet, Sax, Taurus, Violin, Piano, Guitar I and II, Aries, Lunar, Flute—snap in instantly via matrix switches, with a rear tune knob for matching other instruments or glissando fun. Housed in a sleek wood wedge with mono out and aftertouch, it's monophonic but endlessly expressive in a footprint smaller than most Moogs of the era.
Vintage players cherish its raw analog warmth and preset convenience, though its rarity means well-maintained ones command respect—common gripes center on limited tweakability compared to fully modular siblings, but that's part of its quick-change charm.
