Multi-Filter Mono/Paraphonic Synth
Sequential - 'Pro 3'

A Three-Generation LegacyThe Sequential Pro 1 and Pro 2 mono synths have achieved almost legendary status in their time. With that in mind they continued build on their strengths with the result of an even better product. The Pro 3, Sequential’s 2-VCO + wavetable mono/paraphonic synth is a new benchmark for raw sonic power and unmatchable versatility.
With loads of sonic power in a three-octave, semi-weighted keyboard with velocity and channel aftertouch, add backlit pitch and mod wheels and a location-sensitive touch slider, gives you one of the most inspiring synths on todays market.
The Power of 3

Huge RangeThe Pro 3 comes with three oscillators, three vintage filters, three LFOs, four loopable envelopes, a huge 32-slot mod matrix, and a 16 x 16 x 4 sequencer.
Along with dual digital effects and four control voltage ins and outs, and you have a massively powerful instrument that’s as entertaining to program as it is to play.
A Next-Generation Classic

Incredible Tonal PossibilitiesThe Pro 3 is a combination of solid, classic analog synthesis joined with versatile digital technology. Its two voltage controlled oscillators provide warmth and presence where the third wavetable oscillator provides digital edge and grit.
Included are 32 tables of 16 waves each and wave morphing, tonal possibilities are incredible. Tuned feedback with grunge, and analog distortion give you industrial-grade dirt on demand.
A Vintage Modern Hybrid

Three Filters Based On Vintage DesignsBuilt in to the Pro 3’s punchy sound are its vintage-style filters. Filter 1 is a 4-pole low-pass design based on the Prophet-6 filter. Filter 2 is a classic transistor ladder filter with the choice of resonance compensation to deliver the 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 a selectable band-pass mode. An additional Drive control gives you more punch when you really want to get down and dirty.
Expressive Sequencing

Powerful PerformancePotentially the Pro 3’s most powerful performance tool is the sequencer. 16 tracks, 16 steps, and 4 phrases, it features both real-time and step input, ratcheting, variable gate and sequence lengths, multiple playback modes, and paraphonic operation.
On top of that it 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 171-destination modulation matrix.
Works Great With Modulars

Dedicated ControlsThe Pro 3’s divers architecture allows not only processing external audio, but also to interfacing with modular synths through its 4 rear-panel control voltage inputs/outputs and a dedicated gate output.
Control voltages can be assigned and routed from within the modulation matrix and can run at audio rates for intense modulation effects.
Some of the many parameters that can be sent to the CV outputs include oscillators, LFOs, envelopes, and sequencer tracks, which lets the Pro 3 to become the central hub of a modular or multi-synth setup.
Effects & Modulation

More Effects, More CapabilitiesThe Pro 3’s Effects section offers delays, reverbs, time-domain effects including chorus/phasing/flanging and more. There are four loopable five-stage envelope generators, three syncable LFOs with slew and phase offset, a full-featured arpeggiator, and a 32-slot modulation matrix with tons of modulation sources and over a hundred destinations.
Monophonic & Paraphonic Operation

Incredibly ExpressiveThe Pro 3 was designed to be a highly-powerful monosynth, it is also a versatile 3-voice paraphonic synth. This makes playing 3-note chords not only possible, but with creative use of effects and some per-oscillator modulation. Allowing for incerdibly expressive use.
