Sequential Pro 3 SE

3 powerful Oscillators

The magic starts with three oscillators — two analog VCOs and one digital wavetable. The analog oscillators generate three classic wave shapes, triangle, saw, and pulse; each with variable shape modulation/pulse width. The DSP-based digital oscillator produces 32 wavetables of 16 waves each with wave morphing, plus classic sine, triangle, saw, variable-width pulse, and super saw wave shapes. Additionally, digital oscillator 3 can function as an LFO for complex wavetable-based modulation. A fourth sound source — a white noise generator — is accessible via the Mixer section for adding variable grit to any patch.

3 classic analog Filters

The Sequential Pro 3 is a uniquely capable synth, but what really sets it apart are its three classic analog filters. Comprising best-of-the-best VCF topologies from a half-century of analog synthesis, the Pro 3’s filter section includes a 4-pole, 24dB/octave lowpass filter from the Prophet-6; a classic 4-pole, 24dB/octave, transistor ladder filter with variable resonance; and a 2-pole, 12db/octave state-variable OB-6 filter that can be varied continuously between lowpass, notch, and highpass operation, with an optional bandpass mode.

LFOs, Envelopes, Feedback, and Distortion

Onboard the Pro 3 are three syncable LFOs, each with five waveshapes (triangle, saw, reverse saw, square, and S&H), plus phase offset and slew rate. There are four ADSR Envelopes (VCA, Filter, and two Auxiliary). The Envelopes are freely assignable to multiple modulation destinations and they can repeat/loop. When you need sonic hyper-aggression, reach for the Tuned Feedback generator with Grunge. To unleash tonal destruction, crank up the Pro 3’s programmable analog distortion. If you’re in a band, your lead guitarist will have new-found respect for you as you trade searing lead lines and bone-crunching power chords.

The Mod Matrix

Whatever sound you can dream up, you can realize with the Sequential Pro 3. The Modulation matrix adds sophisticated modular synthesis capabilities to the real-time, hands-on immediacy of this powerful performance synth. The Pro 3’s 32-slot mod matrix has over 46 modulation sources and more than 171 destinations. Modulation assignment buttons enable quick and easy modulation routing, while an Amount encoder lets you dial in the ideal blend. So, bend it, twist it, mangle it beyond recognition. That’s the sound of inevitability.

CV I/O and Gate Out

The Pro 3 is equipped with four control voltage (CV) inputs and outputs for interfacing with modular synths and other CV-compatible devices. Parameters that can be sent to CV outputs include oscillators, LFOs, envelopes, sequencer tracks, or any other source within the Modulation matrix. Sequential has also spec’d the Pro 3 with a Gate Out for triggering external CV-compatible devices. Any CV input can be used as a gate input.

Advanced 16-track Sequencer

An advanced Sequencer brings state-of-the-art workstation compositional and sound design prowess to the Pro 3. The Sequencer has three modes: normal, gated, and trigger. With 16 tracks and 4 linkable16-step phrases, the Sequencer features per-step ratcheting, duration, and velocity; as well as forward, reverse, forward/reverse, and random playback modes. It supports real-time and step input, rests, and variable-length sequences, and it syncs to MIDI clock or external audio, as well as CV input. Sequences are freely assignable to any modulation destination.

Sophisticated Arpeggiator

The Pro 3 also features a sophisticated arpeggiator with up, down, up+down, random, and assign modes. It syncs to MIDI clock and external audio and CV inputs and has re-latching capability. It can run simultaneously with the Sequencer to generate arpeggiated patterns with parameter automation.

Amazing pro value

Sequential packed a lot of synthy goodness into the Pro 3. Festooned with over 60 knobs and 70 buttons that enable deep editing with minimal menu diving, the Pro 3 is equally at home onstage and in the studio. It offers 512 factory and 512 user presets plus immediate, real-time controls that let you nail your sounds fast during a live performance, and yet offers comprehensive sound-sculpting capabilities that serious sound designers and composers require. Onstage, you’ll appreciate the Playlist mode that generates set lists of your favorite presets. Ditto the smooth, precise response of the Pro 3’s backlit Pitch and Mod wheels that are easily visible in low-light situations. Another feature we really love is that the Pitch wheel’s upper and lower pitch range are independently adjustable. Also on the left cheek is a latchable, position-sensitive touch slider for enhanced interactivity and control. Topped off with generous professional connectivity, the Sequential Pro 3 is an amazing value. If you’re a serious synthesist, you probably need one.

Designed by a synth legend

Dave Smith was the design engineer and driving force behind the original Sequential Circuits, whose first product was the legendary Prophet 5 in 1977 — the first polyphonic synthesizer capable of storing the value of every parameter within its voicing and control systems. This was a watershed technological breakthrough, and the implications were staggering. Think about this: before the Prophet 5, it simply wasn’t possible to enter a patch number into a synth and recall sounds you had stored. The Prophet 5 and its successors were hugely successful, finding their way into every top studio and major act’s keyboard rig, and onto countless recordings by artists as diverse as Madonna and Weather Report! But Dave Smith’s impressive track record would not be complete without a mention of the major role he played in the development of MIDI. Today, Sequential is back in a big way with cutting-edge synthesizers that incorporate the very best of vintage and modern technologies. Sweetwater is proud to offer to you such a fine line of distinguished musical instruments.
