Description

Fusing the best of vintage and modern synthesis, the Sequential Pro 3 37-key 3-Voice Monophonic/Paraphonic Synthesizer is a powerhouse of sonic creativity. Designed to cater to both studio professionals and live performers, this hybrid synth combines the warmth of analog with the precision of digital technology. The Pro 3 boasts three dynamic oscillators: two analog VCOs for that classic warmth, and a digital wavetable oscillator that adds a gritty edge to your sound palette. Its three iconic filters—inspired by the Prophet-6, OB-6, and the classic ladder filter—offer a vast array of tonal possibilities, from smooth low-pass sweeps to resonant high-pass effects.

Whether you're crafting ethereal soundscapes or driving basslines, the Pro 3's robust modulation matrix, with 32 slots and over 170 destinations, allows for intricate sound design. The 16-track sequencer, complete with real-time and step input, ratcheting, and multiple playback modes, is a composer’s dream, enabling expressive and complex sequences. The Pro 3 is also a modular enthusiast's best friend, featuring four CV inputs and outputs, making it adaptable to any setup. With dual digital effects, programmable distortion, and a user-friendly interface packed with knobs and buttons for minimal menu diving, the Pro 3 is as exhilarating to program as it is to play.

Critic Reviews

Sequential Pro 3 - a new benchmark for raw sonic power - GreatSynthesizers

greatsynthesizers.com

The Sequential Pro 3 is a powerhouse of sonic versatility, delivering a hybrid of analog warmth and cutting-edge digital innovation. This synth excels with its intuitive interface, robust build quality, and a plethora of modulation options. Its standout features include a brilliant step sequencer and user-friendly design, making it a joy for both studio and live use. While the Pro 3 impresses with performance and sound design capabilities, it falls slightly short of its vintage predecessor, the Pro-One, in capturing that elusive analog warmth. Minor gripes include the lack of a direct gate input and some design inconsistencies in the SE model. Despite these, the Pro 3 stands as a compelling instrument, offering immense creative potential and a nod to the legacy of Dave Smith’s synth innovations. Highly recommended for those seeking a modern analog/hybrid synth experience.
