A Three-Generation Legacy
The Sequential Pro 1 and Pro 2 mono synths achieved nearly legendary
status in their time. So it was only natural that we build on their
strengths with an even more worthy successor. Enter the Pro 3,
Sequential’s 2-VCO + wavetable mono/paraphonic synth — a new benchmark
for raw sonic power and unrivalled versatility.
The Power of 3
The Pro 3 boasts three oscillators, three vintage filters, three
LFOs, four loopable envelopes, a massive 32-slot mod matrix, and a 16 x
16 x 4 sequencer. Throw in dual digital effects and four 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
The Pro 3 is a hybrid of solid, old-school analog synthesis paired
with versatile digital technology. Its two voltage controlled
oscillators provide warmth and presence while its third wavetable
oscillator provides digital edge and grit. With 32 tables of 16 waves
each and wave morphing, tonal possibilities are immense. Tuned feedback
with grunge, and analog distortion deliver industrial-grade nastiness on
Three Filters Based on Vintage Designs
At the heart of the Pro 3’s ballsy 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 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.
Possibly the 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
171-destination modulation matrix.
Plays Well with Modulars
The Pro 3’s flexible architecture opens the door to 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 extreme modulation
effects. Some of the many parameters that can be sent to the CV outputs
include oscillators, LFOs, envelopes, and sequencer tracks, allowing the
Pro 3 to become the central hub of a modular or multi-synth setup.
Effects, Envelopes, LFOs, an Arpeggiator, and Extreme Modulation
The Pro 3’s Effects section provides delays, reverbs, time-domain
effects such as 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 dozens of modulation sources and over a hundred
Monophonic and Paraphonic Operation
The 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, very expressive.
Put all of this 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, and you’ve got one of the most
inspiring synths ever made.
