Sequential PRO 3 SE

The Sequential PRO 3 SE is Sequential’s special edition of the new flagship PRO 3. A 2 VCO, wavetable mono/paraphonic synthesizer with a multi-angle tilt-up panel and a full premium-grade walnut finish.

Building on the success of the legendary Sequential PRO 1 and PRO 2 mono synths; the PRO 3 SE well and truly delivers. Sporting unrivaled versatility as well as setting the new benchmark for raw sonic power!

Powerful Sound Engine

Boasting the same powerful sound engine as the standard PRO 3, the special edition ensures you can get the most out of its massive functionality. Including 3 oscillators, 3 vintage filters, 3 LFOs, 4 loopable envelopes, 32-slot mod matrix, and a 16 x 16 x 4 sequencer. What’s more, add in the dual digital effects and four control voltage ins and outs and you’ve got an extremely powerful synthesizer!

Combining old-school analog synthesis with modern digital technology; the PRO-3 SE is a force to be reckoned with. It’s two VCOs provide warmth and presence while the wavetable oscillator gives you that digital edge and grit. Additionally, with 32 tables of 16 waves each, PRO 3 SE gives you unlimited possibilities.

Vintage-Style Filters

Lying at the heart of the PRO 3 SE is a set of vintage-style filters. The first is a 4-pole low-pass design based on the renowned Prophet-6. Then, Filter 2 is a classic transistor ladder filter offering resonance compensation that preserves is low end. Finally, Filter 3 gives you a classic 2-pole, a state-variable design that’s based on the OB-6. Continuously varied between low-pass, notch, and high-pass operation, with an optional band-pass mode. There’s also an additional Drive control that gives you even more punch when you need it most!


One of the most powerful features onboard the PRO 3 SE is its sequencer. Offering 16 tracks, 16 steps, and 4 phrases; you get both real-time and step input; ratcheting; variable gate and sequence lengths; multiple playback modes; and paraphonic operation. While it also syncs to MIDI clock and external audio input, and inputs/outputs control voltages. Finally, the sequence tracks can control any parameter in the 171-destination modulation matrix.

Packed with Effects

What’s more, the Sequential PRO 3 SE boasts an effects section that’s rampant with delays, reverbs and time-domain effects. Including chorus, phasing, flanging and more. There are also four loopable five-stage envelope generators, three sync-able LFOs, an arpeggiator, and a 32-slot modulation matrix.

The PRO 3 SE Final Say

Finally, the Sequential PRO 3 SE is a super-powerful mono synth. But it’s also an extremely versatile 3-voice paraphonic synth. Allowing you to play 3 note chords as well as make creative use of effects and per-oscillator modulation. Above all, the PRO 3 SE has to be one of the most inspiring synths ever made.
