The PS-3300 from Cherry Audio is a meticulously crafted virtual analog recreation of Korg's semi-modular analog polyphonic synthesizer originally released in 1977. With only around 50 units ever produced, the PS-3300 has become a highly sought-after holy grail for synthesists and sound designers. Cherry Audio has painstakingly recreated every element of this monstrous polysynth, from its massive stacked tone and signature resonant sweeps to its considerable patching potential through 67 input and output jacks.

Three Independent Synth Panels for Unparalleled Polyphony

At the heart of the PS-3300 are three synth panels, each essentially functioning as an independent polyphonic synthesizer. Every panel includes 12 tunable oscillator banks, filters, envelope generators and VCAs for all 48 notes of the keyboard. This allows for every key to be played simultaneously with independent articulation, resulting in a thick, complex tone that evolves dynamically over time.

Dual LFOs and Triple Resonators Shape a Characteristic Sound

In addition to its polyphonic architecture, the PS-3300 is equipped with dual LFOs and three voltage-controlled resonators for each synth panel. These modules work together to impart the PS-3300 with its recognizable sonic signature, capable of everything from subtle pulsing effects to dramatic, sweeping timbre changes.

A Fully-Featured Master Panel Provides Advanced Sound Design

A dedicated master panel offers mixing with VCAs for each synth panel, as well as sample and hold, an extra envelope generator and two control voltage processors. These modules furnish a diverse range of modulation and control possibilities for crafting complex patches and textures. Between its three synth panels and master panel, the PS-3300 delivers an astounding level of sound design flexibility.

An Iconic Polysynth, Reimagined for Today

Cherry Audio's virtual recreation of the Korg polysynth brings this legendary machine into the modern age. Musicians and sound designers can now experience the PS-3300's analog tone and explore its semi-modular architecture without prohibitive cost or scarcity. For those seeking a powerful, characterful polysynth, the PS-3300 delivers an iconic vintage instrument reborn.
