The construction of synthesizers from expensive discrete components, rather than more accessible oscillator and filter chips, made polyphonic instruments not only costly but also lacking in features.

[6] The PS-3100 was the smaller model and employed a 'divide-down' oscillator architecture, previously utilized in Keio's Polyphonic Ensemble synthesizers, but with significant enhancements.

It featured a comprehensive selection of modules, an ensemble effect, and a patch panel with 32 inputs and outputs for flexible sound routing.

[9] It boasted over 60 patch points and included additional features such as sample & hold, a global envelope generator, two voltage processors, independent channel outputs, and mixers for its three synth sections.

The low-pass voltage-controlled filter (VCF) features cutoff frequency and resonance controls, allowing modulation from both the LFO and the envelope.

Additionally, the 60-pin PS-3001 cable facilitated the connection of up to three Korg PS series synthesizers to one keyboard through the PS-3050 junction box, enabling centralized control.

[6][11] The PS series ceased production by 1981, leading Korg to focus on developing more conventional polysynths, such as the Polysix, Poly-61, and DW synthesizers.

[12] In October 2023, Cherry Audio released a software emulation of the PS-3300, created with the Electronic Music Education and Preservation Project (EMEAPP).

It comes with AU, VST, VST3, AAX and standalone formats and extends the original features by adding PS- or MS-style filter selection, tempo sync, temperament tuning presets and an effects section.

This reissue incorporates digital patch storage with 16 banks, each containing 16 slots, USB and MIDI connectivity, and a librarian application for preset organization.
