Sequential Prophet REV2 8-Voice Poly Synth

Dave Smith Instruments REV2,
 

a new 16-voice / or 8-voice analog synthesizer designed to be a successor to the Prophet ’08.

Like its predecessor, the REV2 features two DCOs per voice and Curtis filters at the heart of its sound engine, but boasts a number of significant enhancements designed to make it more powerful.

As Dave Smith puts it, “The Prophet ’08 has been a real road warrior for 10 years now and people still love it. But we felt it was time to update it with new technology and new features and, at the same time, lower its cost.” Smith continued: “The REV2 is essentially the result of our effort to enhance and improve everything we could about the original Prophet ’08 and, in many cases, double its power.”

The most obvious difference between the REV2 and its predecessor is polyphony. The REV2 has 16-voices as its standard configuration — twice the polyphony of the Prophet ’08 (though an 8-voice option is also available). Since the synth features bi-timbral operation, two completely independent sounds can be stacked or split — layered together or assigned to two different zones on the keyboard.

The essence of its sound comes from two DCOs (plus a sub-octave generator on oscillator 1) per voice, with 4 waveshapes (sawtooth, triangle, sawtooth + triangle, and pulse) and a 2/4 pole low-pass, resonant Curtis filter per voice. These are the same filters used not only in the Prophet ’08, but also in many classic instruments of the ’70s and ’80s. A new feature unique to the REV2 is waveshape modulation. You can vary the “pulse width” of any of the four waveforms by manually dialing in a desired waveshape width or by using an LFO or other modulation source for continuously shifting timbre.

An effects section provides reverb, delays (standard and BBD), chorus, phase shifter, ring modulation, and distortion. In stacked or split voice mode, you can apply a different effect to each layer. Effects parameters can be modulated through the mod matrix, which is twice as extensive as its predecessor, with 8 individual slots and many more sources/destinations.

A new polyphonic step sequencer allows up to 64 steps and up to 6 notes per step. A different sequence can be created for each layer when working in stacked or split voice mode. A separate gated sequencer functions as a modulation source, allowing you to create up to 4 different 16-step sequences for complex modulation. Sequences allow ties and rests, and can sync to an external MIDI clock. The arpeggiator features note repeats, re-latching, and can be synced to external MIDI clock, as well. Other improvments include a premium-quality, five-octave, semi-weighted keyboard with velocity and channel aftertouch, an integrated power supply, USB support, and a crisp OLED display.

“We’ve created a monster,” says Dave, “and I mean that in the best possible way.”

A Modern Classic Reinvented

The REV2 is Dave Smith’s reimagining of his Prophet ’08 poly synth — a modern classic that has appeared on countless recordings and stages since its debut in 2007. As Dave puts it, “The REV2 is the realization of our effort to enhance and improve everything we could about the original design — all at a more accessible price.”

The REV2 retains all of the key features of the Prophet ’08 and expands on them. It has twice the polyphony, twice the mod matrix, waveshape modulation on all waveforms, digital effects per layer in stacked or split voice mode, a polyphonic step sequencer per layer, and more. The result is a true analog powerhouse.

Best of all, you can download any of the many existing libraries of Prophet ’08 sounds and they will not only sound identical, but can be enhanced with the new features.

16-Voice Polyphony

With 16 voices to play with, you have the freedom to allocate them as you wish. Play two-fisted chords, stack two 8-voice sounds for massive, complex textures, or split the keyboard into two completely separate 8-voice instruments.

Bold Sound

The REV2 gets its bold, punchy sound from its 2/4 pole, low-pass, resonant Curtis filters per voice. These are the same filters used not only in the Prophet ’08, but in many classic instruments of the 70’s and 80’s. A separate Audio Mod control adds additional harmonic complexity and movement.

Waveshape Modulation
A powerful new feature unique to the REV2 is waveshape modulation. You can now vary the “pulse width” of any of the four waveforms (sawtooth, saw+tri, triangle, square). Using the Shape Mod control, you can manually dial in a desired waveshape width or use an LFO or other mod source for continuously shifting timbre. Even single-oscillator sounds take on new depth and dimension. The tonal possibilities are vast.

Effects Per Layer
The effects section provides reverb, delays (standard and BBD), chorus, phase shifter, ring modulation, and distortion. In stacked or split voice mode, you can apply a different effect to each layer. Effects parameters can be modulated through the Mod Matrix.

Extended Mod Matrix
Also present from its predecessor is an easy-to-assign Mod Matrix, now twice as big, with 8 individual slots and many more sources/destinations. It’s a veritable sound designer’s playground.

Poly Step Sequencing
The polyphonic step sequencer allows up to 64 steps and up to 6 notes per step. You can create a different sequence for each layer when you are working in stacked or split voice mode, making it a powerful tool for composition or performance. The sequencer also functions as a modulation source in gated mode, allowing you to create up to 4 different 16-step sequences for complex modulation. Sequences allow ties and rests, and can sync to an external MIDI clock. The arpeggiator features note repeats, re-latching, and can be synced to external MIDI clock, as well.

Per-Knob Programmability
The knob-per-function front panel offers instant access to REV2 functions. Included are 512 permanent factory programs and 512 rewritable user programs.

Eminently Playable
All of this polyphonic power is packed into a five-octave, premium-quality, semi-weighted keyboard with velocity and channel aftertouch. Other road-worthy features include an integrated power supply, USB support, and a crisp OLED display, making the REV2 an ideal instrument for gigging or recording, and an analog powerhouse like no other.
