Description

HYBRID MULTI-FILTER MONOSYNTH

As the modern successor to the legendary Pro-One, the Sequential Pro 3 monosynth represents the company’s most powerful and full-featured synthesis architecture to date. Drawing on decades of innovation, this instrument unlocks sonic possibilities inconceivable on any other synth.

The Pro 3 synthesizer is a supersonic science lab with its powerful array of tone-shaping tools. Combining wavetable and analog oscillators, three distinct analog filter types, and 3-note paraphonic operation, this instrument opens up new synthesis frontiers for exploration.

Dive into the Pro 3’s full spectrum of shape-shifting wavetables, while simultaneously basking in the organic warmth of analog synthesis. This unique combination invites you to craft new sounds that are both groundbreaking and timeless.

At the heart of the Pro 3’s dynamic sound are its three analog filters: a low-pass design inspired by the original Prophet-5, a classic transistor ladder, and a 2-pole SEM filter that can morph between modes. This trio of filters makes the Pro 3 voice path one of the most powerful and flexible of all Sequential synthesizers.

At the moment of inspiration, who wants to be pulled away from their instrument? With the Pro 3’s comprehensive onboard pattern sequencer, you can capture ideas immediately, then quickly add expressive modulations simply holding the Play button and twisting a knob.

The Pro 3’s extensive I/O options make it the ultimate command center for your electronic music studio. With multiple CV/Gate inputs and outputs, it seamlessly connects to modular systems and vintage synths, while its MIDI I/O ensures compatibility with all your modern gear.

The Pro 3 is available in two tasty flavors: one with an adjustable top panel and one without. In an homage to classic analog synths, the controls of the Pro 3 SE can angle upward, providing enhanced visibility and easy access to the knobs during sound design and performance.

Oscillator 3 features digital wavetables that expand your sonic palette beyond traditional analog waveshapes. It includes 32 factory wavetables, each containing 16 unique waves with smooth morphing for dynamically evolving timbres. Sequential also offers a web-based Wavetable Generator utility to convert single-cycle waves into Pro 3-compatible SysEx files, ensuring easy integration of up to 32 custom wavetables.

The Pro 3 synthesizer supports Patch Morphing, allowing musicians to seamlessly transition between two distinct programs in real-time using performance controllers like the touch slider and mod wheel. This expressive capability enables users to “play” the morph, creating complex and evolving sounds that surprise and inspire.
