Pro 3 SE Hybrid Keyboard (Special Edition)

KeyboardHybridParaphonic

Ever since Sequential nodded to the Minimoog's iconic tiltable panel, synth designers have chased that perfect hands-on angle, and this special edition nails it with a premium walnut-trimmed control surface that adjusts just right for any setup.

At its core, it's a hybrid powerhouse with two analog VCOs dishing out classic warmth, plus a wavetable oscillator packing 32 tables of 16 waves each—complete with morphing, custom imports via their web-based generator, and a supersaw option for digital bite. Shape tones through three legendary filters: a Prophet-6 4-pole lowpass, a transistor ladder with resonance compensation, or the OB-6's 2-pole state-variable multimode (lowpass, highpass, notch, bandpass). Four loopable 5-stage envelopes, three syncable LFOs with slew, and a 32-slot mod matrix hitting 171 destinations keep things wildly expressive, while dual digital effects—think stereo/BBD delay, reverb, phaser, flanger, ring mod, rotary, and grunge—add polish or filth. The 37-key semi-weighted keyboard responds to velocity and channel aftertouch, paired with backlit pitch/mod wheels, a position-sensitive touch slider, and a 16x16x4 paraphonic sequencer that locks parameters for evolving leads, basses, or textures.

Players love how it bridges monosynth grunt with 3-note paraphonic chords, making it a modular hub via 4 CV/Gate ins/outs, and that sequencer turns live sets into sonic adventures—though some wish for poly aftertouch. In Sequential's lineup, it stands tall as the raw, performance-driven evolution of the Pro-One legacy.
