Sequential Pro 3 Special Edition Multi-Filter Mono/Paraphonic Synth with Walnut Trim

The Sequential Pro 3 Special Edition is a hybrid mono/paraphonic synthesizer that combines modern digital capabilities with classic analogue warmth. Building on the heritage of the Pro 1 and Pro 2 models, it features a three-octave semi-weighted keyboard with velocity and channel aftertouch, plus a location-sensitive touch slider and modulation wheels. This special edition version distinguishes itself with high-quality walnut trim and a tilt-up control panel, offering both aesthetic appeal and practical ergonomics. The instrument's core architecture revolves around sets of three: three oscillators (two analogue voltage-controlled oscillators plus one DSP-based digital wavetable oscillator), three syncable LFOs with phase and slew offset, and three distinct vintage-style filters. These include a 4-pole Prophet-6 low-pass filter, a transistor ladder filter, and a 2-pole OB-6 state-variable filter. The hybrid design allows for extensive sound design possibilities, from classic analogue tones to evolving digital textures via 32 wavetables of 16 waves each, with wave morphing capabilities. A 16-track, 16-step, 4-phrase sequencer provides comprehensive sequencing options with step and real-time input, while a 32-slot modulation matrix offers immense routing flexibility. The Pro 3 SE operates equally well as a monophonic or 3-voice paraphonic instrument, enabling three-note chords with per-oscillator modulation. It includes dual digital effects such as stereo delay, chorus, flanger, phaser, and plate reverb, plus a fully-featured arpeggiator. The synth supports extensive connectivity with modular systems via control voltage inputs and outputs, and can process external audio. With user wavetable import functionality and the recent patch morphing feature introduced in the 1.2 operating system update, it serves as a versatile centrepiece for both studio production and live performance setups.
