PS-3300 Black Friday Deal 2026: $24, 51% off

The ps 3300 Black Friday deal from Cherry Audio takes 51% off the PS-3300 synth plugin, so it costs $24 until Nov 27, 2026.

PS-3300 is a virtual analog emulation of the semi-modular polyphonic synthesizer Korg released in 1977. Cherry Audio says it recreates and updates the original, from its stacked sonic character and multiple-resonator sweeps to its patching.

What is the PS-3300?

The hardware was the largest and most expensive of Korg's Polyphonic Series, built between 1977 and 1981. Around 50 units were made, which makes it one of the rarest analog synths around.

Bob Moog reportedly called it "the best synthesizer for fat sounds." Vangelis, Jean-Michel Jarre, Aphex Twin, Kraftwerk, Klaus Schulze and Keith Emerson are among the artists who used it.

How the PS-3300 plugin is built

The design has three independent signal generator panels, and each one works as a complete polyphonic synth. In the original, every panel carries 12 tunable divide-down oscillator banks, with separate VCFs, envelopes and VCAs per note.

A master panel adds a mixer with a VCA for each generator, sample & hold, an extra envelope generator and two control voltage processors. The original had 67 front-panel jacks, and the plugin keeps the virtual jack and cable system.

Main features

• Three generator panels, each with VCOs offering six waveforms: triangle, saw, rectangle, two preset pulse widths and PWM
• 12 dB/oct resonant lowpass filters, switchable between the standard PS filter and a crunchier MS-style filter
• Three modulatable resonators per generator: 12 dB/oct bandpass filters for vowel and phasing tones
• Two syncable mod generators (LFOs) per generator
• Temperament section with presets for Equal Tempered, Mean Tone System, Hepatonal System and Just Intonation
• Up to 24 voices, plus three mono modes: last, low and high note priority
• Unlimited mults per jack, with customizable cable color, transparency and animation
• Built-in chorus, echo with sync, and spring, plate and Galactic reverbs

Settings can be copied and pasted between generator panels. Each channel has its own panning, and bend range and master tune are user-adjustable.

Presets, formats and system requirements

Over 360 presets come in a dozen categories. A bonus Legacy collection follows the patch sheets from the original owner's manual, and there is a 3100-based Glissando patch and a 432 Hz Equal Temperament patch.

It runs as a standalone instrument and as a plug-in. Every control takes MIDI control and DAW automation, with MIDI Learn and mapping. Oversampling is adjustable, and the Focus zoom-in feature is included.

On macOS you need 10.13 or above, 64-bit, with native Apple M1 and later support. On Windows, 7 or above including 11, 64-bit. Cherry Audio recommends a 3.4 GHz quad-core CPU with 8GB of RAM on either system.
