Check the listing for details. Sequential Fourm Compact Polyphonic Analog Synthesizer. Condition: New. Listed at 899.99 USD. The Sequential Fourm compact polyphonic analog synthesizer delivers the soul of classic analog synthesis in a compact, hands-on unit. Built around the Prophet-5 voice structure, this synth features dual oscillators with simultaneous waveform selection and a 4-pole low-pass filter. The addition of bass compensation boosts low-end response, giving every patch more punch. Polyphonic aftertouch on the 37-note slim-key keyboard lets you bend notes or swell chords, unlocking expressive techniques not possible on most polysynths. With intuitive top-panel modulation, the unit is designed for musicians who want immediate access to sound-shaping tools—without menu-diving.
