Sequential FOURM

Fourm is a compact analog synthesizer that gives you an unprecedented level of expressiveness. Combining Sequential's legendary sound with practical modulation functions and a responsive keyboard, Fourm lets you bring your musical ideas to life like no other synth.

Reinventing a legendary analog sound

Fourm's four voices are based on the architecture of the famous Prophet-5, right down to the envelope curves. Enjoy Sequential's true analog sound, with two oscillators for simultaneous waveform selection and a classic 4-pole low-pass filter with bass compensation. The Fourm delivers a punchy, warm character that has marked a whole generation of musicians.

A new Fourm of expression

The Fourm keyboard features 37 thin keys with polyphonic aftertouch, allowing you to perform expressive techniques like guitar bendings, swells and other nuanced articulations. It revolutionizes modern analog polyphonic synthesizer playing.

Modulation you can touch

The Pro-One-inspired modulation matrix is located on the front panel for easy sound design without navigating complex menus. You can route sources and destinations at the touch of a button, visualize connections with color-coded indicators, and create complex modulation paths in seconds. Fast, intuitive and designed to never interrupt your creativity.
