Sequential Fourm – the new four-voice analogue synthesizer has arrived at Wired Tunes! Compact yet powerful, this instrument fuses the legendary Prophet-5 heritage with modern versatility for today’s musicians.
A new chapter of classic tone
Sequential Fourm features dual oscillators with selectable waveforms, a 4-pole low-pass filter with bass compensation, and drive for added punch. Each of its four voices delivers the warm, dynamic analogue sound of the Prophet lineage, now paired with modern reliability and precision.
Expressive playability
The 37-note slim-key keyboard with polyphonic aftertouch enables advanced performance techniques – from smooth bends to expressive swells. Every nuance of your playing translates directly into sound, making the Fourm a perfect tool for live performers and studio creators alike.

Hands-on sound design
Inspired by the Pro-One, the Sequential Fourm top-panel modulation matrix and knob-per-function design simplify routing and make complex modulation instantly accessible. With 128 presets, an arpeggiator, and sequencer mode, it offers both immediacy and depth for all styles of electronic music.
Connectivity for every setup
Equipped with USB MIDI, full MIDI I/O, and expression pedal inputs, the Sequential Fourm integrates seamlessly into modern studio and live rigs. Its steel chassis ensures durability, while the compact footprint makes it practical for any environment.
