The latest addition to Dave Smith's revered Prophet synthesizer line is here! 12 fat voices with tons of features!

The Prophet 12 is a 12-voice polyphonic synthesizer with an advanced digital/analog hybrid voice architecture capable of creating eminently playable, dynamic, and innovative sounds unlike any other synthesizer. Using 35 years of experience building synths, Dave Smith has created what he calls his “best synth yet.” By combining the finest qualities of the Prophet '08 and Poly Evolver keyboards, adding a ton of new features, and bumping up the voice-count to 12, the Prophet 12 is well worthy of the name. As with all Dave Smith keyboards, the Prophet 12 has a knob-per-function interface that lets you start designing sounds immediately without having to dive through pages of confusing menus.

At twelve voices, the Prophet 12 boasts the greatest polyphony of any instrument designed by Smith. Each voice features four oscillators capable of generating classic and complex waveforms, a sub-oscillator, resonant analog low- and high-pass filters, and analog VCAs. The new Character section adds a variety of wave shaping and sound sculpting options, like Drive, Hack, Decimation, Girth, and Air. Additional features include a tuned feedback path, a four-tap stereo delay per voice, expanded arpeggiator functionality, deep modulation capabilities, and bi-timbral operation. The LFOs, delay, and arpeggiator can all be synced, either to the internal clock or an external MIDI clock. Two programmable position- and pressure-sensitive touch sliders take the performance controls beyond the standard pitch and mod wheels (also included).



  • Five DSP-based oscillators per voice (including one sine wave sub oscillator)
  • Four classic wave shapes (saw, square, triangle, sine) per oscillator
  • Twelve selectable complex shapes per oscillator
  • Three noise types per oscillator: white, pink, violet
  • Shape modulation
  • Oscillator cross modulation: frequency modulation (FM) and amplitude modulation (AM)
  • Hard sync on each of the four oscillators

Character Effects

  • Five high-quality digital effects. Thicken the signal and add harmonics or completely destroy the signal pre-filter.
  • Girth and Air are high and low shelf equalizers with harmonic excitement. Useful for thickening and/or adding air to the signal.
  • Hack and Decimate are sample and bit rate reduction algorithms which can add subtle grit or completely destroy the signal. It's harsh yet musical!
  • Drive is a soft saturator for adding soft distortion and harmonic content to the signal


  • Famed Curtis 2- or 4-pole resonant analog low-pass filter (self oscillates in 4-pole mode) per voice
  • 2-pole resonant analog high-pass filter per voice

Feedback and Delay

  • Tuned feedback
  • Four-tap syncable multi delay with feedback and amount per delay per voice


  • Four Delay + ADSR envelopes (LPF, VCA , and two Auxiliary envelopes)
  • Auxiliary envelopes 3 and 4 freely assignable to multiple modulation destinations
  • LPF and Auxiliary envelopes can repeat/loop.


  • Four syncable LFO's with phase offset and slew per LFO


  • 16 x 2 modulation matrix with over 100 mod destinations
  • Modulation assignment buttons enable quick and easy modulation routing


  • Sophisticated programmable arpeggiator with up, down, up+down, random, assign modes
  • Re-latching arpeggiator

Programmable Distortion

  • Independent programmable stereo analog distortion per layer.


  • More than 50 knobs and 50 buttons enable deep and comprehensive editing with little to no menu diving.
  • Backlit pitch and mod wheels are easily visible in low light situations and have a smooth yet precise feel and response.
  • Independently adjustable upper and lower pitch wheel range.
  • Two assignable position- and pressure-sensitive latchable touch sliders for enhanced interactivity and control.
  • Full-sized, 5-Octave, semi-weighted keyboard with velocity and channel aftertouch


  • 396 user and 396 factory programs
  • Direct program access using numeric keypad and dedicated User, Factory, and Bank buttons
  • Playlist mode for generating easily accessible setlists of your favorite programs. Create four play lists with up to forty programs each!


  • 1 MIDI In, 1 MIDI out, and 1 MIDI Thru port
  • USB port for bidirectional MIDI communication
  • 1 Sustain/footswitch input
  • 2 expression pedal inputs
  • Main stereo output (2 x 1/4" phone jack)
  • Layer B stereo output (2 x 1/4" phone jack)
  • Headphone out (stereo 1/4" phone jack)
