Sequential Prophet-5 Keyboard Synthesizer

The Prophet-5 has returned! The Sequential Prophet-5 "Rev 4" combines the authentic, lush sound of the original with the reliability of a state-of-the-art modern instrument.

The Sequential Prophet-5 “Rev 4” is Dave Smith's return to the analog poly synth that changed the world. It’s “the best of all Prophet-5s” because it embodies all three revisions of the legendary synth—Rev1, Rev2, and Rev3—through the use of genuine Curtis analog VCOs and filters (as in the Rev3) as well as new 2140 low-pass filters designed by Dave Rossum, the modern equivalent of the 2040 filters he designed in the original Rev1 and Rev2. A Rev switch lets you choose between the two filter designs.

The result is as pure a renewal of an analog classic as you could wish for, with the authentic, muscular sound of the original and the roadworthiness of a state-of-the-art modern instrument.

To give even more authentic mojo to the new Prophet-5, Sequential created the Vintage knob. Use it to dial in as much old-school randomness as you’d like and it will loosen up the oscillators and envelopes just like they were in the good old days. It lets you dial in progressively more vintage character as you go from a stable 4 (as in Prophet-5 Rev4) all the way to 1 (as in Prophet-5 Rev1, the rarest and most temperamental of all Prophet-5s).

The Prophet-5 includes the original 40 Prophet-5 factory sounds.

Sequential Prophet-5 Features:

• Authentic reimagining of the original Prophet-5 in look and sound
• 5 voices, with velocity and aftertouch, MIDI, and a premium Fatar keyboard
• Authentic vintage CEM VCOs
• Authentic vintage Doug Curtis and Dave Rossum-designed filters (switchable)

Vintage Sound, Vintage Knob

In addition to sourcing genuine Prophet-5 hardware components, Sequential did extensive research into exactly what made the original sound the way it did — warm, organic, and alive. They found that much of this desirable character was due to slight fluctuations and differences in the response times and frequencies of the individual VCOs, filters, envelopes, and amplifiers from voice to voice.

To give the same mojo to the new Prophet-5, Sequential created the Vintage knob. Use it to dial in as much old-school randomness as you’d like. Go from a very stable “4” — as in Prophet-5 Rev4, which is how we refer to the new version in house — all the way to “1,” as in Prophet-5 Rev1, the rarest and most temperamental of all Prophet-5s.

Poly Mod and Enhanced Unison

In addition to the unmistakable tone of its oscillators and filters, much of the classic sound of Prophet-5 was the result of Poly Mod, which is faithfully present here as well. True to the original, modulation sources are Filter Envelope and Oscillator B. Destinations include Oscillator A frequency, Oscillator A pulse width, and low-pass filter. The range of sounds possible defy its simplicity. Another welcome reprise is Unison mode, which now features configurable voice count (1-5 voices) with variable detuning, and chord memory. And now Glide works both in and out of Unison.

Velocity and Aftertouch

Though Sequential's mission was to make the new Prophet-5 as accurate, authoritative, and true to the original as possible, they couldn’t resist adding a couple of modern enhancements to increase expressiveness: velocity sensitivity and aftertouch. These enable the new Prophet-5 to perform in ways the original never could by putting filter sweeps, LFO mod, and volume changes at your fingertips.

Effortless to Program

The purity of the new Prophet’s sound is matched only by its simplicity to program. The knob-per-function front panel gives you instant gratification and immediate access to all sound-shaping controls. Toggling off the Preset button enables live panel mode, where the Prophet-5 switches to the current settings of its knobs and switches. What you see is exactly what you hear. Included are 200 permanent factory programs and 200 rewritable user programs, including the original 40-program sound set from 1978 that found its way onto countless recordings and film soundtracks back in the day and beyond.

The Whole Package

All of this punchy, powerful, analog goodness is housed in a full, five-octave, semi-weighted Fatar keyboard with USB, MIDI, Gate and CV ins/outs, and a premium-quality, steel and hand-oiled, sustainable black walnut heartwood body that make it as satisfying to behold as it is to hear and play.
