The Rumor is true – Pro 3 is real

Uptown Oscillators nailed it, we prophesized this September 16, 2019 on this Pro 3 page and earlier May 17, 2019 on our Sequential Pro 2 page.

Back in May 2019, Dave Smith did say a new synth “hopefully will be out in September-ish”  with no other details. That didn’t happen, then I theorized NAMM 2020 would be it.

A Pro 3 Trademark was applied for by Sequential back in September 2019.

I can’t speak for the market, but an informed synthesist knows there is nothing quite like a Sequential Pro 2; it clobbers every other keyboard class monophonic/paraphonic synth made. A Pro 3 would have to be an amazing machine to take its place. It is a very high bar to reach over that has been set by the Pro 2.

First of all, both Pro 3 models look great, especially the SE with its ala Moog hinge and the traditional woods. The Pro 3 includes both analog and digital oscillators with wavetables. The sequencer is killer. The 4 knob/4 button screen interface is a familiar joy.

I’m sure the high end paraphonic synthesizer market is a tough place to play, but after the initial sparkles wore off, I am seeing a few major changes here. I think it is very important to approach the Pro 3 as a whole new synth. It is not a souped up Pro 2.

The Pro 3 has 37 keys instead of 44. It is in line with the Moog Subsequent 37. This is the critical comparison here I think. Sequential/Dave Smith Instruments synths have always been Moog killers. In fact, when I decided to put the Pro 3 on my 2020 buy list, it was mainly to replace my Subsequent 37. I love the Moog, but I’m an even bigger fan of the Sequential screen/knob workflow, and now with analog oscillators, the Moog would be even further isolated in my gear, so I’m selling it.

With all 3 oscillators, the Pro 3 has 3 paraphonic voices instead of the Pro 2’s 4 voices. To be clear though, you can only do 2 of those voices with the exact same oscillators (analog). I think many will really like the analog oscillators. You could stick to some of the classic wave shapes on all 3 oscillators (analog and digital) to get fairly similar paraphonic voices. Some might consider 3 voices with 2 distinct types of oscillators to be somewhat unusual, however in my opinion, the unusual would be very desirable and exactly what you want.

My Pro 2 use is lead, bass, percussion, heavily sequenced or modulated sounds. It is not my go to poly. I have 2 flagship polyphonics; I am not looking for the Pro 3 to do chords or pads. Paraphonic is the most I need and most of the time mono. Dave Smith did his homework here, the market yearned for analog oscillators and the price is still in a range it doesn’t have to compete with high-end polys.

The 3rd digital oscillator does look interesting, with 32 digital wavetables of 16 waves each with wave morphing, plus classic wave shapes (sine, triangle, saw, variable-width pulse) and super saw and can function as an LFO for complex wavetable-based modulation. Obviously, the Pro 3 is no Waldorf Quantum, but I’m 100% certain that is not Sequential’s intention. Dave Smith says they are considering adding the capability for user supplied wavetables or Sequential supplied wavetables in a future firmware update.

There are 3 filters on the Pro 3, an upgrade from 2. However, you can only use them one at a time. There is no serial, parallel, or split oscillator routing. Dave Smith says it would get messy routing 3 filters, and most of the time routing a low-pass through a low pass wouldn’t make sense.

There is 1 latchable position-sensitive touch slider instead of 2, without pressure-sensitivity. There are 3 LFOs instead of 4, and to be exact, the wavetable is really your 4th LFO, and its abilities would be a real upgrade to the LFO palette.

The Pro 3 improves on the Pro 2 capabilities to function as your control center synth. In addition to MIDI in, MIDI out 1, MIDI thru and MIDI out 2, it has 4 CV inputs, 4 CV outputs and a gate output. The 16 track 64 step sequencer outputs to CV and all other modulation destinations. All the extensive modulation sources output to CV as well.

The Pro 3 looks like a real contender, I expect it to outsell the Pro 2. I know many of us dreamed of what now could be a Pro 4, with twice the goodies (personally, I would have liked 2 analogs and 4 digitals, others might want 4 analogs and 2 digitals); either of those would have really extended the paraphonic stratosphere, but the Pro 3 is definitely a Moog Subsequent killer. I think in actual use, it will pair well with a Prophet X or Quantum, just like the Pro 2 already does.

If you are fortunate enough to have a Sequential Pro 2, keep it!

“Combining a Sequential Pro 2 and Pro 3 creates a monster synth system… 7 oscillators, 5 filters, 7 envelopes, 32 lanes of note, parameter and CV sequencing, 8 assignable CV Ins, 8 assignable CV Outs, and I’m not even going to try to count the modulation possibilities.” -Chris Stack

Product Description

A Three-Generation Legacy

The Sequential Pro 1 and Pro 2 mono synths achieved nearly legendary status in their time. So it was only natural that we build on their strengths with an even more worthy successor. Enter the Pro 3, Sequential’s 2-VCO + wavetable mono/paraphonic synth – a new benchmark for raw sonic power and unrivalled versatility.

The Power of 3

The Pro 3 boasts three oscillators, three vintage filters, three LFOs, four loopable envelopes, a massive 32-slot mod matrix, and an 16 x 16 x 4 sequencer. Throw in dual digital effects and four control voltage ins and outs, and you’ve got a hugely powerful instrument that’s as exciting to program as it is to play.

A Next-Generation Classic

The Pro 3 is a hybrid of solid, old-school analog synthesis paired with versatile digital technology. Its two voltage controlled oscillators provide warmth and presence while its third wavetable oscillator provides digital edge and grit. With 32 tables of 16 waves each and wave morphing, tonal possibilities are immense. Tuned feedback with grunge, and analog distortion deliver industrial-grade nastiness on demand.

Three Filters Based on Vintage Designs

At the heart of the Pro 3’s ballsy sound are its vintage-style filters. Filter 1 is a 4-pole lowpass design based on the Prophet-6 filter. Filter 2 is a classic transistor ladder filter with optional resonance compensation to preserve its low-end punch. Filter 3 is a classic 2-pole, state-variable design based on the OB-6 filter that can be continuously varied between lowpass, notch, and high-pass operation, with an optional band-pass mode. An additional Drive control provides still more punch when you really want to get down and dirty.

Expressive Sequencing

Possibly the Pro 3’s most powerful performance tool is its sequencer. With 16 tracks, 16 steps, and 4 phrases, it features both real-time and step input, ratcheting, variable gate and sequence lengths, multiple playback modes, and paraphonic operation. It also syncs to MIDI clock and external audio input, and inputs/outputs control voltages. In addition to notes, sequence tracks can control any parameter in the 132-destination modulation matrix.

Plays Well with Modulars

The Pro 3’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/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, allowing the Pro 3 to become the central hub of a modular or multisynth setup.

Effects, Envelopes, LFOs, an Arpeggiator, and Extreme Modulation

The Pro 3’s Effects section provides delays, reverbs, time-domain effects such as chorus/phasing/flanging and more. There are four loopable five-stage envelope generators, three syncable LFOs with slew and phase offset, a full-featured arpeggiator, and a 32-slot modulation matrix with dozens of modulation sources and over a hundred destinations.

Monophonic and Paraphonic Operation

The Pro 3 was designed to be a super-powerful monosynth, but it is also a versatile 3-voice paraphonic synth. This makes playing 3-note chords not only possible, but with creative use of effects and some per-oscillator modulation, mind-blowingly expressive.
Put all of this sonic power in a three-octave, semi-weighted keyboard with velocity and channel aftertouch, add backlit pitch and mod wheels and a location-sensitive touch slider, and you’ve got one of the most inspiring synths ever made.
