The Pro 2 is Dave Smith’s flagship mono synth. 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.”
Two New Filters Based on Vintage Designs
At the heart of the Pro 2’s 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 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 loopable 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.
Four DSP-based oscillators plus 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/pulse width/superwave detune amount
Oscillator cross modulation: frequency modulation (FM) and amplitude modulation (AM)
Hard sync, individual Glide, Oscillator Slop
True 4-voice paraphonic mode with individually-gated envelopes per oscillator
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
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.
Five Delay + ADSR envelopes (Filter 1, Filter 2, VCA , and two Auxiliary envelopes)
Auxiliary envelopes 4 and 5 freely assignable to multiple modulation destinations
All envelopes can repeat/loop
Four syncable LFOs with phase offset and slew per LFO
16 x 2 modulation matrix with over 50 mod sources and over 140 mod destinations
Modulation assignment buttons enable quick and easy modulation routing.
Mod Matrix runs up to audio rates.
CONTROL VOLTAGE INS & OUTS AND GATE OUT
Four 1-volt-per-octave control voltage inputs and outputs for interfacing with modular synths and other CV-compatible devices
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.
