One Voice to Rule Them All. The Pro 2 is Dave Smith’s flagship mono synth, and as Dave himself puts it, his “most powerful mono synth ever.” The Pro 2 shares the same exceptional ergonomics and playability as its 12-voice sibling, the Prophet 12, but carves out distinctly different sonic territory with an all-new dual analog filter architecture, a monster step sequencer, superwaves, digital bucket-brigade delay, and a lot more. Nothing else sounds like it and nothing else performs like it. It raises the bar for monosynths and redefines the word “fat.”
Dave Smith Instruments Pro 2 Keyboard Features

- Drive is a soft saturator for adding soft distortion and harmonic content to the signal
- Dual analog filters operate in serial or parallel
- Filter 1 is a 4-pole resonant analog low-pass filter inspired by the original Prophet-5 filter.
- Filter 2 is a 2-pole resonant analog state-variable filter inspired by the Oberheim SEM filter and can be continuously varied between low-pass, notch, and high-pass operation, with an optional band-pass mode.
- Oscillator Split allows oscillators 1 & 2 to be sent to Filter 1 and oscillators 3 & 4 to Filter 2.
- Feedback and Delay:
- Tuned feedback
- Three-tap syncable delays with feedback and amount controls, pan, and high-pass and low-pass filtering, all per delay. A separate fourth delay is a digital bucket-brigade delay (BBD) for analog-style effects.

- Parameters that can be sent to CV outputs include oscillators, LFOs, envelopes, sequencer tracks and any other source within the modulation matrix. Runs up to audio rates
- Gate Out for triggering external CV-compatible devices; any CV in can be used as a gate input.
- Advanced step sequencer with two modes: 16 steps x 16 tracks or 32 steps x 8 tracks

- Syncs to MIDI clock and external audio and CV inputs
- Re-latching arpeggiation
- Programmable Distortion: Stereo analog distortion
- More than 50 knobs and 65 buttons enable deep and comprehensive editing with minimal 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, three-and-a-half-octave, semi-weighted keyboard with velocity and aftertouch
- Memory: 396 user and 396 factory programs; Playlist mode for generating easily accessible setlists of your favorite programs
The Pro 2 is a fusion of classic analog synthesizer design and cutting-edge digital technology. It boasts four high-resolution digital oscillators, plus a sub oscillator. The oscillators produce both classic and complex wave shapes and can frequency and amplitude modulate each other in any operator and modulator configurations you choose for harmonically-rich FM and AM sounds. A set of Character controls adds high and low frequency boost, bit and sample rate reduction, and tape saturation emulation to the Pro 2′s sonic palette.
Two New Filters Based on Vintage Designs
At the heart of the Pro 2′s gutsy sound is its all-new dual filter design. Filter 1 is a 4-pole low-pass design inspired by the original Prophet-5 filter. Filter 2 is a state-variable design inspired by the Oberheim SEM and can be continuously varied between low-pass, notch, and high-pass operation, with an optional band-pass mode. The two filters function in either serial or parallel, or anywhere in between. Two of the four oscillators can be routed through Filter 1 with the other two routed through Filter 2 for a broad range of tonal possibilities.
One of the most exciting features of the Pro 2 is its sequencer—possibly the most powerful step sequencer ever designed for a synth. With up to 32 steps and 16 tracks, it provides real-time input, rests, and variable-length sequences. It also syncs to MIDI clock and external audio input. Sequence tracks can control any parameter in the Pro 2′s extensive modulation matrix.
Plays Well with Modulars
The Pro 2′s flexible architecture opens the door to not only processing external audio, but also to interfacing with modular synths through its 4 rear-panel control voltage inputs and outputs and a dedicated gate output. Control voltages can be assigned and routed from within the modulation matrix and can run at audio rates for extreme modulation effects. Some of the many parameters that can be sent to the CV outputs include oscillators, LFOs, envelopes, and sequencer tracks, making the Pro 2 a natural choice for the center of your studio or live setup.
Delays, Envelopes, LFOs, Arpeggiator, and a Multitude of Modulation
The Pro 2′s delay section provides three digital delays with pan, and high-pass and low-pass filtering controls. A fourth delay is a digital bucket-brigade delay (BBD) for analog-style effects. There are four loop-able five-stage envelope generators, four syncable LFOs with slew and phase offset, a full-featured arpeggiator, and a sixteen slot modulation matrix with dozens of modulation sources and destinations.
Monophonic by Design, Paraphonic by Choice
The Pro 2 was designed primarily as a super-powerful monosynth, but it’s also a true, four-voice paraphonic synth that allows you to control each of its four oscillators individually with their own envelope. This makes playing four-note chords not only possible, but very expressive. Package all of this power in a three-and-a-half octave, semi-weighted keyboard with velocity and channel aftertouch, add two backlit pitch and mod wheels and two location and pressure sensitive touch sliders, and you’ve got one of the most feature-rich, awe-inspiring synthesizers ever created.
