Sequential has launched a new 4-voice analog synthesizer with polyphonic aftertouch. A compact synth that invites you to play, shape, and perform with unprecedented expression, Fourm comes with the legendary Sequential tone, hands-on modulation, and uniquely responsive Tactive™ keybed to bring your musical ideas to life.
Fourm delivers four genuine voices of Sequential analog sound, built on the legendary Prophet-5 voice architecture—right down to its characteristic envelope response curves. With dual oscillators offering simultaneous wave selection and a classic 4-pole low-pass filter with bass compensation, Fourm captures the warmth and punch that shaped a generation—and takes it to the next level.
From its solid steel chassis to the custom-engineered Tactive slim-keys keybed with responsive polyphonic aftertouch, every element of Fourm was designed to deliver a fully integrated, high-performance playing experience. It’s a no-compromise, all-analog instrument, built for the next generation of synthesists.
