Dave Smith Pro 2

The Pro 2 from Dave Smith is widely considered his most powerful mono synth. With the warmth and presence of analog filters and VCAs and the precision of digital clocks and oscillator sync, this hybrid synthesizer has everything one needs to make a huge sounding synth without the drift and instability of analog oscillators. It has a built in step sequencer and delay, turning the Pro 2 into a miniature workstation. 

Two filters are present on the Pro 2, a 4-pole lowpass filter inspired by the original Prophet 5 filter, as well as a state-variable SEM style filter inspired by Tom Oberheim, which can switch between lowpass, bandpass, highpass, and notch filter types. The two filters can be run in series (for variable bandwidth if lowpass and highpass are used creatively together) and in parallel for complex timbres and resonances. 

The sequencer in the Pro 2 is extremely powerful. It has 32 steps on 16 different tracks with real time input, rests and variable length sequences. Synchronizing the Pro 2 to an external MIDI clock or running external audio thru the filter/FX is as simple as plugging in the appropriate cable. 

With the Eurorack Modular community expanding rapidly, the Pro 2 has some patch points for interfacing with modular gear. Four CV outputs and four CV inputs can be assigned to control virtually any part of the synthesizer. Oscillators can be sent dry out of a CV output, as can LFOs, envelopes, making it a wonderful master controller and sound source even when focusing on modular synthesis. 

Because the Pro 2 has two oscillators per voice, (four oscillators total), it is possible to turn the Pro 2 into a Paraphonic synthesizer, meaning it can simulate polyphony. The difference between paraphony and true polyphony is based on the filters and envelopes. In true polyphony, each oscillator (voice) has its own filter, envelope and VCA. In paraphony, the filters and envelopes are shared, but each oscillator can be tuned to a note in the chord. This allows one to play punchy chord, expanding the Pro 2's functionality outside of the "mono synth" category. 

All this with a three and a half octave, semi-weighted keyboard with velocity and aftertouch makes the Pro 2 one of the most powerful synthesizers on the market. 

Pro 2 Features

  • Four DSP-based oscillators plus one sine wave sub oscillator
  • Four oscillator classic wave shapes (saw, square, triangle, sine) per oscillator
  • Twelve selectable complex shapes per oscillator
  • 13 Superwaves
  • 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
  • Five high-quality digital effects
  • 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 trash the signal. It's harsh yet musical
  • 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
  • Tuned Feedback
  • Three-tap syncable delay 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
  • Parameters that can be sent to CV outputs include oscillators, LFOs, envelopes, sequencer tracks and any other source within the modulation matrix
  • Mod Matrix runs up to audio rates
  • Gate Out for triggering external CV-compatible devices; any CV in can be used as a gate input
  • Four 1-volt-per-octave control voltage inputs and outputs for interfacing with modular synths and other CV-compatible devices
  • Modulation assignment buttons enable quick and easy modulation routing
  • Mod Matrix runs up to audio rates
  • Advanced step sequencer provides up to 32 steps per sequence and up to 16 tracks
  • Supports real-time input, rests, and variable-length sequences
  • Syncs to MIDI clock and external audio and CV input
  • Sequences can control not only oscillator pitch but any parameter in the modulation matrix
  • Sophisticated arpeggiator with up, down, up+down, random, assign modes
  • Supports real-time input, rests, and variable-length sequences
  • Re-latching arpeggiation
  • Programmable Distortion: Stereo analog distortion
