SEQUENTIAL Prophet Rev2 8-voice Module

Sequential Prophet Rev2 8-Voice Module is a desktop hybrid polyphonic synthesizer with analog Curtis filters, digital effects per layer, extensive modulation options, and a powerful polyphonic step sequencer. Designed as a compact yet fully featured version of the Prophet Rev2 Keyboard, it delivers the same expressive power and intuitive control in a rack-friendly format.

As a reimagining of the iconic Prophet ’08, the Rev2 enhances the classic architecture with an expanded modulation matrix, waveform shape modulation, digital effects per layer, per-layer polyphonic sequencing, and more. This 8-voice version allows for layered, split, or stacked configurations and can be upgraded to 16 voices with an optional expansion kit.

The sound engine is powered by two digitally controlled analog oscillators and a white noise generator, routed through resonant Curtis low-pass filters with selectable 2- or 4-pole slopes—known for their character in classic 70s and 80s synthesizers. Shape Mod allows for manual or modulated control of waveform symmetry across saw, triangle, and pulse waves, creating evolving textures and timbres.

Each layer has its own dedicated effects engine, offering reverbs, delays (standard and BBD), chorus, phaser, ring modulator, and distortion. Effects parameters can be modulated using the expanded 8-slot modulation matrix, which includes 22 sources and 53 destinations.

The polyphonic step sequencer supports up to 64 steps with 6-note polyphony per step and can run independently for each layer in split or stacked mode. The hands-on interface features 55 knobs and 35 buttons for one-knob-per-function control, a crisp OLED display, and support for USB, MIDI, and full program recall with 512 factory and 512 user presets.
