Sequential gives away Fourm, a compact analog synth with Prophet-5 roots

Sequential’s Fourm giveaway puts a prize on the kind of synth that makes vintage-minded players stop and read the panel before they read the rules. The instrument at the center of it is a compact, 100 percent analog four-voice keyboard built from Prophet-5 voice architecture, with dual oscillators, a classic 4-pole low-pass filter, envelope curves modeled after the 1978 original, and overdriven feedback for extra bite. The competition runs through Sunday, May 31, 2026, and the winner is scheduled to be notified by Monday, June 8, 2026.

What gives Fourm its appeal is not just the spec sheet, but how plainly it speaks Sequential. The front panel borrows its look from the Pro-One, and the layout keeps that old Sequential instinct for direct control alive: knob-forward, menu-free, and easy to read at a glance. Add in 37 slim keys, 128 presets, and an arpeggiator-sequencer mode, and the instrument reads less like a nostalgia exercise than a compact modern board built to feel immediate under the hands.

The biggest talking point remains the keybed. Fourm uses a custom Tactive slim-keys design co-developed to support polyphonic aftertouch, a feature that has become rare enough to feel almost archival in a new analog synth. Sequential has said Fourm marked its return to polyphonic aftertouch after more than four decades, which explains why the instrument landed as more than another small-format launch. It was also positioned as Sequential’s most affordable synth at launch, widening the audience for a design that still wears the company’s classic DNA so openly.

Sequential tied the giveaway to its official site, where the company points visitors to specs, audio examples, and a top-panel tour. The contest prize is one Fourm synthesizer keyboard, and eligibility is limited to residents of participating territories, with the competition void where prohibited or restricted by law.

The giveaway is the hook, but the reason Fourm keeps resurfacing in conversation is simpler: it packages Prophet-5 lineage, Pro-One ergonomics, and true poly-AT into a compact analog synth that looks ready for a modern setup without shedding the Sequential identity that collectors and players still recognize instantly.
