Sequential proudly unveils Fourm — a compact, expressive analog synthesizer designed to inspire. With its iconic Sequential tone, hands-on modulation, and a uniquely responsive keybed, Fourm is a creative partner that brings musical ideas to life.
Legendary Analog Sound, Reimagined
Built on the legendary Prophet-5 voice architecture, Fourm delivers four true analog voices with the unmistakable warmth and punch that defined a generation. Dual oscillators with simultaneous wave selection and a classic 4-pole low-pass filter (now with bass compensation) ensure that every note hits harder than the last.
A New Fourm of Expression
Fourm’s 37-note slim-key keyboard features polyphonic aftertouch, unlocking expressive techniques like guitar-style note bends, solo voice swells, and other nuanced articulations—completely transforming the experience of playing a modern Sequential polysynth.
Modulation You Can Touch
Inspired by the Pro~One, Fourm’s top-panel modulation matrix puts deep sound design at your fingertips. Route sources and destinations instantly, visualize connections with color-coded LEDs, and build complex mod paths in seconds — no menu diving, just pure creative flow.
