Sequential Fourm – a compact 4-voice analogue synthesizer built on the legendary Prophet-5 architecture, combining vintage warmth with modern flexibility. Its dual oscillators allow simultaneous waveform selection, while a 4-pole resonant low-pass filter with bass compensation delivers the iconic Sequential character. The 37-note slim-key keyboard with polyphonic aftertouch provides expressive performance capabilities such as note bends and voice swells, making it highly responsive to nuanced playing. A knob-per-function layout and top-panel modulation matrix inspired by the Pro-One make sound design fast and intuitive, eliminating the need for menu diving. With 128 factory presets, an arpeggiator with sequencer mode, and rugged all-steel construction, Fourm is equally at home in the studio and on stage. Connectivity includes MIDI (in/out/thru), USB MIDI, and pedal inputs, ensuring seamless integration into any setup.
