Description

Reinventing a legendary analog sound
Fourm’s four voices are based on the architecture of the legendary Prophet-5, right down to the envelope curves. You’ll enjoy the true Sequential analog sound. With its two oscillators allowing simultaneous waveform selection and its classic 4‑pole low-pass filter—now featuring a bass compensation function—Fourm brings a fresh dimension to the punchy, warm character that shaped the sound of a generation.

A new Fourm of expression

Fourm’s keyboard features 37 slim keys with polyphonic aftertouch, so you can perform expressive techniques like guitar-style bends, swells, and other nuanced articulations. It revolutionizes performance on a modern analog polyphonic synth.

Modulation at your fingertips
The modulation matrix, inspired by the Pro-One, is located on Fourm’s front panel so you can craft sounds easily without menu diving. Route sources to destinations with a single button press, visualize connections via color-coded indicators, and build complex modulation paths in seconds. This matrix is fast, intuitive, and designed to never interrupt your creativity.
