Back in the 1970s, this synth pioneered a dual-signal-path design that let you run two independent voices through separate oscillators, filters, and amps—like packing two monosynths into one compact box for duophonic tricks via CV/gate.
Its two analog VCOs deliver sawtooth and pulse waves with PWM, FM capabilities, and independent portamento sliders, mixable with noise or external input for gritty textures. Dual 12dB/octave multimode filters (low-pass, band-pass, high-pass) offer resonance and self-oscillation, controlled together by the standout 'Brilliance' slider or split for sweeps, while two ADSR envelopes (switchable to 5x speed) shape VCF and VCA per channel. A single LFO with saw-down, sine, and sample & hold modulates pitch, filters, or amps, all accessed via the intuitive front-panel signal flow diagram on its 37-key (C-C) keyboard chassis—754mm wide, 10kg heavy, with mono low/high outputs, headphone jack, and dual CV/gate ins/outs.
Players love its raw, characterful tones for blips, basses, and experimental processing, praising the filter flexibility and near-modular routing that set it apart from fatter Moogs. Sure, it's strictly mono from the keys without extra gear, and no sine on the VCOs, but that pushes creative workarounds vintage heads swear by.
