The essence of the Prophet Rev2’s sound comes from two DCOs per voice with four waveshapes (sawtooth, triangle, sawtooth + triangle, and pulse), a sub-octave generator, 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 Prophet 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.
The 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. The sequencer also 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.
