Pro 3 Hybrid Keyboard

KeyboardHybridParaphonic

Ever since Sequential brought back the hybrid spirit of classic wavetable designs, this beast has been a go-to for players craving that perfect blend of raw analog growl and digital morphing magic.

It packs two analog VCOs for thick, warm tones alongside a wavetable oscillator drawing from 32 tables—each with 16 waves—plus the ability to import your own custom wavetables for endless sound design possibilities. A punchy analog filter shapes everything, fed by four envelopes and three LFOs, all routed through a 32-slot mod matrix with 171 destinations that lets you twist parameters into wild territory. Tuned feedback adds grit, while onboard effects like reverb, delay, phaser, flanger, ring mod, and drive give polished finishes without external gear. The 37-key semi-weighted keyboard feels responsive with velocity and channel aftertouch, paired with a touch slider, arpeggiator, and 16-track 16-step sequencer handling up to four phrases—ideal for live jamming or studio sequencing. Hands-on knobs cover oscillators, filter, envelopes, and more, with a compact 26.5" x 13" x 3.5" metal chassis that fits anywhere, complete with stereo outs, mono audio in, headphone jack, four CV ins/outs, and sustain/expression pedal inputs.

Players love its intuitive workflow and monstrous paraphonic 3-note mode for huge leads and basses, though some note the monophonic limit keeps it focused rather than poly sprawling. It's earned a spot as Sequential's powerhouse hybrid, bridging their Prophet legacy with wavetable innovation in a rig that's as stage-ready as it is studio-deep.
