NAMM 2020 VIDEO: Sequential shows us its latest flagship synth, the Pro 3

NAMM 2020: It’s been a little while since Dave Smith’s Sequential brand announced a new synthesizer (opens in new tab), so we were quietly expecting something new for this year’s NAMM show. Following an initial leak, Sequential has now officially unveiled its latest flagship synth, the Pro 3 – and it looks great!

The Pro 3 is a three-oscillator paraphonic synth that combines both analogue and digital components. There are two analogue oscillators each with saw, triangle and variable-width pulse waves. These are joined by a DSP-powered digital oscillator that can produce 32 types of morphing wavetable, along with analogue oscillator emulations and a supersaw mode. 

This DSP oscillator can also function as a complex wavetable LFO for interesting modulation possibilities. There’s also an additional noise generator, plus controls for hard sync, per-oscillator glide and a Slop feature for introducing analogue-like inaccuracies.

There are three analogue filter types onboard - a Prophet-6 LPF, a Moog-style ladder filter and the continuous, state-variable design from the OB-6. The ladder filter here includes an optional resonance compensation feature to maintain bass presence even with the resonance cranked. The OB-6 model also has a bandpass switch to complement its morphable low-pass, notch and high-pass modes. The inclusion of a drive control lets users add a touch of grit at the filter stage too. 

On the modulation front, the synth has four freely-assignable, looping ADSR envelopes plus three syncable LFOs with phase-offset and slew. A 32-slot modulation matrix with 171 possible destinations should allow for copious amounts of routing options.

On the digital side of things, the Pro 3 has dual effects sections boasting multiple types of reverb, delay and modulation effects including chorus, phasers and flangers. It also promises a programmable analogue distortion and tuned feedback for aggressive tonal effects.

While the Pro 3 is a monosynth at heart, it can also be used in a three-voice paraphonic mode with individually gated envelopes per-oscillator.

Finally, the package is rounded off by a powerful-looking sequencer with 16 tracks, each capable of 16 steps and four phrases. On its rear, the hardware has four CV inputs and outputs, plus a gate out, and it seems the sequencer can be used to control the synth itself and external hardware simultaneously. 

The Pro 3 will be available in two forms, the standard model (pictured below) and a hinged, wooden-ended special edition version (top). Both versions have a 37-note keyboard. There's also a multimode arpeggiator included.

“In many ways the Pro 3 is the evolution of a concept that started with the classic Sequential Circuits Pro-One,” says 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.”

The standard version is due for release by the end of January, priced at $1599 and the wooden paneled special edition will arrive in February with a price of $2099. Find out more at the Sequential site.
