Bonus Item

Sequential's Pro 1 and Pro 2 mono synths achieved nearly legendary status in their time, so it was only natural that they build on their strengths with an even more worthy successor. Enter Sequential Pro 3, a 2-VCO + wavetable mono/paraphonic synth and a new benchmark for raw sonic power and unrivaled versatility.

The power of 3
Pro 3 boasts 3 oscillators, 3 vintage filters, 3 LFOs, 4 loopable envelopes, a massive 32-slot mod matrix and a 16×16×4 sequencer. Throw in dual digital effects and 4 control voltage ins and outs and you've got a hugely powerful instrument that's as exciting to program as it is to play.

A next-generation classic
Pro 3 is a hybrid of solid, old school analog synthesis paired with versatile digital technology. Its 2 voltage-controlled oscillators provide warmth and presence, while its 3rd wavetable oscillator provides digital edge and grit. With 32 tables of 16 waves each and wave morphing, the tonal possibilities are immense. Tuned feedback with grunge and analog distortion deliver industrial-grade nastiness on demand.

Three filters based on vintage designs
At the heart of Pro 3's ballsy sound are its vintage-style filters. Filter 1 is a 4-pole lowpass design based on the Prophet-6 filter. Filter 2 is a classic transistor ladder filter with optional resonance compensation to preserve its 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 an optional band-pass mode. An additional drive control provides still more punch when you really want to get down and dirty.

Expressive sequencing
Possibly Pro 3's most powerful performance tool is its sequencer. With 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. It also 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 132-destination modulation matrix.

Plays well with modulars
Pro 3's flexible architecture opens the door not only to 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 extreme modulation effects. Some of the many parameters that can be sent to the CV outputs include oscillators, LFOs, envelopes and sequencer tracks, allowing Pro 3 to become the central hub of a modular or multi-synth setup.

Effects, envelopes, LFOs, an arpeggiator and extreme modulation
Pro 3's effects section provides delays, reverbs, time-domain effects such as chorus/phasing/flanging and more. There are 4 loopable 5-stage envelope generators, 3 syncable LFOs with slew and phase offset, a full-featured arpeggiator and a 32-slot modulation matrix with dozens of modulation sources and over 100 destinations.

Monophonic and paraphonic operation
Pro 3 was designed to be a super-powerful monosynth, but 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, mind-blowingly expressive.

Put all of this sonic power in a 3-octave, semi-weighted keyboard with velocity and channel aftertouch, add backlit pitch and mod wheels and a location-sensitive touch slider and you've got one of the most inspiring synths ever made.
