The Essentials to Know About the Prophet-5 Rev4 Synthesizer
- Authentic 5-voice polyphonic analog sound, true to the Prophet DNA, with real VCOs and two switchable filter models.
- Exclusive "Vintage" knob to dial in the character of different revisions (Rev1/2/3) and recapture the organic instability of the original machines.
- Fatar 61-note semi-weighted keyboard with velocity and aftertouch for expressive playing both in the studio and on stage.
- Modern workflow: 400 presets (200 factory + 200 user), direct program access, MIDI/USB, audio, CV/Gate, and pedals.
A Faithful Reissue Bringing Together the Three Legendary Revs
With the "Rev4," Sequential delivers a carefully crafted tribute to the original Prophet-5 by combining, in a single instrument, the sonic soul of the Rev1/2 and Rev3. The CEM 3340 VCOs and selectable analog filters - Curtis as on the Rev3, or the 2140 low-pass filter designed by Dave Rossum as a nod to the 2040s of the early series - recreate the muscular grain and dynamic response that marked the history of analog polysynths.
Who Is It For and For What? From Live Performance to Original Soundtrack Creation
The Prophet-5 Rev4 is aimed at discerning keyboardists, producers, and sound designers seeking an immediate analog poly for electro, synthwave, pop, techno, ambient, or scoring. Its ergonomic simplicity suits motivated beginners, while its tonal richness and classic modulations will appeal to advanced and expert users in studio, live, or sound experimentation contexts.
Features and Innovations
The synthesis is decisively subtractive: two VCOs per voice with simultaneously selectable waveforms, hard sync, and a 4-pole resonant low-pass filter per voice. The "Vintage" knob finely modulates the behavior of oscillators, envelopes, and amplifiers to shift from modern stability to a more capricious patina. ADSR envelopes, aftertouch, and velocity provide expressive nuances, while program management offers direct Prophet-style access to eight immediate sounds. Connectivity covers MIDI DIN In/Out/Thru, USB, audio, as well as CV and Gate I/O for modular interaction. Construction blends steel and hand-oiled black walnut, resulting in an instrument that is both robust and elegant.
