A software version of KORG's rare 1977 PS-3300, a fully polyphonic analog synth used by Kraftwerk and Jean-Michel Jarre, modeled with Component Modeling Technology.

What it does

The PS-3300 plugin is KORG's own recreation of its 1977 PS-3300, a rare fully polyphonic analog synth with an independent voice on every key; fewer than 50 were built. It uses KORG's Component Modeling Technology to model the octave-divider oscillators and circuits of the three synth units and the patch panel that links them.

Voices: three synth racks with 60 voices each, 180 in total, each with its own modelled quirks; the original had three voices on each of its 48 keys.
Filters: a choice of the smooth PS-3300 filter or the more aggressive MS-20 filter.
Envelopes: separate filter and amp envelopes or one shared envelope, with original PS-3300 or modern exp/log curves, plus a velocity-sensitive ADSR.
Resonators: three-band resonators for vocal, string or metallic colour, which can be modulated for phasing and wah-like movement.
Patch panel and modulation: semi-modular patching with smart cables that show signal flow and block invalid connections, Multiplier, Attenuverter and Lag processors, LFOs, and a 30-slot mod matrix for aftertouch, mod wheel, pitch bend and X-Y control.
Effects: a built-in Ensemble modelled on the PS-3100/3200, plus 31 insert and reverb effects.
Extras: import of programs from the hardware PS-3300 reissue, tempo sync and a wider pitch range.

It was released in October 2025 as part of KORG Collection 6 and is also sold alone.

When to use it

The PS-3300 is the pick for rich, slightly unstable analog polyphony and patched textures with a strong 70s character. Compared with Arturia CS-80 V, it is more semi-modular, with a patch panel, resonators and three stacked synth racks instead of a fixed panel. Next to Diva it is less of an all-round analog workhorse and much heavier on CPU, but it gives sounds that few other plugins reach. Synth Anatomy found it more refined and more analog-sounding than Cherry Audio's PS-3300, the other main software version.

Best for: lush strings, organ-like chords, evolving pads, vocal-like resonant tones and experimental patched textures.
Genres: electronic, ambient, synth-pop, film and experimental music.
Look elsewhere if: you want a quick preset synth or a light CPU load; Diva or CS-80 V are easier to drive, and Cherry Audio's PS-3300 is another take on the same instrument.
Tip: modulate the resonators with an LFO for phaser and wah-style movement, as Synth Anatomy suggests.

What producers say

Early reviews call it a highlight of KORG Collection 6, with high CPU use the main drawback.

Synth Anatomy (October 2025) called it "arguably the highlight" of Collection 6 and said it sounds "juicy, has a lot of bottom", more refined than Cherry Audio's version.
Dubspot blog (October 2025) praised it for making authentic analog polyphony that was once "prohibitively expensive" widely accessible.
Criticisms: Synth Anatomy measured 15% to 40% CPU on an M1 Max, and missed a loop mode for the LFOs and a way to split the voice racks across the keyboard.
