SEQUENTIAL PRO 3 - Sounds, Patches and Presets | Synth Demo

Published on Feb 10, 2020 synth4ever

"Sequential PRO 3 SE synthesizer demo, featuring various sounds, patches and presets. Filmed at Sequential headquarters, this Sequential PRO 3 demo features a variety of sounds including leads, basses, pads, textures, percussion, arpeggiators and sequencer patterns.

The Sequential PRO 3 is a hybrid multi-filter mono synthesizer with 60 knobs and 70 buttons, FATAR 37-note semi-weighted keyboard and 3-voice optional paraphony mode (feat. individually gated envelopes per oscillator). The PRO 3 features 3 oscillators (two VCOs + one wavetable), 3 analog filters, 3 LFOs, 4 loopable envelopes, noise, hard sync, glide, tuned feedback, analog distortion, arpeggiator, 16x16x4 sequencer + 16-track sequencer, dual digital effects engines, touch slider and mod wheels, and a staggering 32-slot mod matrix.

The PRO 3's two analog VCOs each have triangle, saw, pulse waveshapes, with variable shape modulation/pulse width on each. The digital oscillator features 32 digital wavetables of 16 waves each (with wave morphing), plus classic wave shapes (sine, triangle, saw, variable-width pulse) and super saw. The PRO 3's digital osc can also function as an LFO to enable complex wavetable-based modulation.

The Sequential PRO 3 has three filter types, which provide a variety of sound shaping options. Filter 1 is a 4-pole, 24 dB, Prophet-6 low-pass filter. Filter 2 is a classic, 4-pole, 24 dB, transistor ladder filter (w/ optional resonance compensation). Filter 3 is a 2-pole, 12 db, OB-6 state-variable filter which can be continuously varied between low-pass, notch, and high-pass operation, with an optional band-pass mode.

The PRO 3's three syncable LFOs each have phase offset and slew per LFO, and feature five waveshapes: triangle, saw, reverse saw, square, and S&H. There are 4 loopable ADSR envelopes with delay (Filter, VCA, + two Auxiliary envelopes); envelopes are freely assignable to multiple modulation destinations.

The PRO 3 also features dual digital effects, including: Stereo delay, BBD delay, chorus, flanger, phaser, ring mod, vintage rotating speaker, distortion, high-pass filter, super plate reverb. Also on board is analog distortion and tuned feedback (with Grunge mode), for extra-aggressive tonal destruction.

The PRO features a huge 32-slot modulation matrix, with over 46 mod sources and over 171 mod destinations. This allows for a massive amount of sound design possibilities and creative applications. Modulation assignments can be done quickly and easily, and the Mod Matrix runs at audio rates.

The PRO 3's advanced sequencer has three modes: normal, gated, and trigger. There are 16 tracks and 4 linkable 16-step phrases with per-step ratcheting, duration, and velocity as well as multiple playback modes: forward, reverse, forward/reverse, random. The PRO 3 sequencer supports real-time/step input, rests, and variable-length sequences and syncs to MIDI clock and external audio and CV input. Sequences are also freely assignable to any modulation destination.

Also on board the Sequential PRO 3 is a sophisticated arpeggiator with up, down, up+down, random, assign modes. The arp syncs to MIDI clock and external audio and CV inputs, supports re-latching arpeggiation, and runs concurrent with Sequencer for arpeggiated patterns with parameter automation.

In terms of connectivity, the Sequential PRO 3 has 4 CV inputs and 4 CV outputs which enables interaction with other modular or CV-compatible devices. For example, some parameters that can be sent to CV outputs include oscillators, LFOs, envelopes, sequencer tracks and any other source within the modulation matrix. In addition the PRO 3 has Gate Out for triggering external CV-compatible devices, and any CV in can be used as a gate input.

Needless to say, the Sequential PRO 3 is a powerhouse of a monosynth and allows for incredibly deep and complex sound design. The sound can be big, bold, powerful and aggressive but also delicate, airy and atmospheric depending how you program it. The 2 analog VCOs + wavetable oscillator also open up new combinations of sound design that, when combined with the 32-slot mod matrix, provides unparalleled flexibility.

Overall it was an incredible experience to try the PRO 3 SE synth when visiting Sequential headquarters. I filmed nearly 2.5 hours of footage and this demo highlights some of the patches on the machine. I came away extremely impressed with the possibilities from this synth, it is certainly one of the most flexible monos of all time and sounds fantastic. Hope you enjoy this PRO 3 demo.
