Sequential Debuts the Pro 3 - Multi-Filter Mono Synth

Update: some audio demos added below.

"Some time ago, I put together a video demonstrating the remarkable ability of the AS-1 synthesizer to mimic the classic Sequential Circuits Pro One. I sent the video to my friends at Sequential and expressed a great desire for a fully fledged, keyboard version of the synth. Flash forward to the tail end of 2019, and I’m sitting in front of the Sequential Pro 3. While the inspiration might have come from some aspects of the AS-1, the Pro 3 is so far and above, it truly deserves the title of FLAGSHIP.

To me, the central point of the Pro 3 isn’t necessarily the feature set, which is VAST, but the raw sound. This synth is a production workhorse that sounds proper. It has a kind of aggression, bigness, and elegance that is typically associated with some of the finest vintage synthesizers; the low end is massive and the top end can cut through but it’s that all important midrange that is the most impressive. That midrange synthesizer bass sound, that many other synths fail at (by over compensating lows and highs) isn’t an issue here and it’s that aspect that allows the Pro 3 to link the vintage to the modern. Simply put, any working producer looking for a flagship mono that can handle the rigor of modern production and can make as many classic vintage sounds as futuristic ones should not sleep on this.

The three filters on offer here all have their unique personalities and allow you to cover a vast array of sounds. The OB6 filter in particular is a favorite and combined with the sheer physicality of the analog vco’s used here, allowed me to get into a kind of Xpander territory. The ladder filter pounds and moves like a vintage synth. And the Prophet 6/AS1 filter is exactly what you expect.

No external sequencing or multitracking was used on this recording. Everything was made 100 percent on the Pro 3. This is a recording of all of the patches I submitted to Sequential for the Pro 3’s factory bank. A big thanks to the whole Sequential family and a massive congratulations from INHALT on this stunning new synth!"

"Sequential Debuts Pro 3, Multi-filter Mono Synth Featuring VCOs, Wavetables

San Francisco, CA—January 14, 2020—Sequential today announced the Pro 3, a new flagship mono/paraphonic synthesizer. A hybrid instrument, the Pro 3 features three classic analog filters (Prophet-6, OB-6, and ladder) and three oscillators (two VCOs and one wavetable oscillator) along with a powerful new 16-track sequencer, and the ability to connect with modular synths through its four control voltage ins/outs.

“In many ways the Pro 3 is the evolution of a concept that started with the classic Sequential Circuits Pro-One,” said Sequential founder Dave Smith: “Pack as much power as possible into a compact footprint and make it sound awesome. To do that, we built on the strengths of its modern-day counterpart, the Pro 2, and created a worthy successor to both that sets a new benchmark for raw power and versatility.”

Part of this sonic versatility comes from the Pro 3’s oscillators: Two voltage controlled oscillators provide traditional triangle, saw, and pulse waves with waveshaping, while a third digital wavetable oscillator provides 32 tables of 16 waves each with wave morphing. Three vintage-style filters shape the sound of these oscillators. Filter 1 is a 4-pole low-pass 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 low-pass, notch, and high-pass operation, with an optional band-pass mode. A Drive control provides additional punch to all three filters.

The feature set of the Pro 3 is rounded out with a multimode arpeggiator, three LFOs, four loopable ADSR+delay envelopes, dual digital effects (delays, reverbs, and various time-based effects), tuned feedback, analog distortion, and extensive modulation possibilities. The LFOs, delay, and arpeggiator can be synced to either the internal clock or an external MIDI clock. A programmable position-sensitive touch slider and pitch and mod wheels provide nuanced control over live performance. The synth is also capable of 3-voice paraphonic operation. This makes it possible to play 3-note chords where the three individual oscillators share a common filter and envelopes.

The full-featured sequencer provides 16-track sequences of up to 64 steps, with 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 32-slot, 171-destination modulation matrix.

Another key feature of the Pro 3 is its four scalable rear-panel control voltage inputs and outputs, which allow compatibility with modular synths. Control voltages are routed from within the modulation matrix and run at audio rates for extreme modulation effects. “We wanted to make the Pro 3 as flexible as possible,” said Smith. “The CVs and deep mod matrix make it a mini modular in its own right — without all the patch cables.”

Sequential is also offering the Pro 3 SE, a special edition version of the synthesizer that puts the same synthesis power into a collector-worthy design that features a tilt-up control panel and full, premium-grade walnut trim.

The Pro 3 standard edition will be available at the end of January with a US MAP of $1,599.

The Pro 3 SE will be available in February with a US MAP of $2,099."

  1. It seems all the experimentation happened before 2005. Even the Motor Synthesizer is only replicating the work put into mechanical sine wave synthesizers of the 1920s. Analog, digital, wavetable, VA, back to analog, wavetable again. These are all trends going 'round in a circle. I suppose everyone will be playing steam calliopes in 2021.
