Cherry Audio PS-20 A Polyphonic, ‘Hot-Rodded’ Korg MS-20 Synthesizer

Cherry Audio has introduced PS-20, a new software synthesizer that they describe as an “ultra-realistic, polyphonic, hot-rodded tribute to Korg’s renowned MS-20”.

They say that they’ve recreated the MS-20’s iconic sound, but also have redesigned the patch panel from the original, adding patch points for all oscillators, filters, and VCAs, ‘correcting the confusing terminology of the original’, and improving its usability.

The PS-20 architecture has been “souped up” compared to the original, with 16-note polyphony; a unique three-layer, eight-step sequencer with flexible CV outs; and integrated effects, including a distortion, modulation echo with stereo spread, and a reverb with spring and plate emulations.

It also builds on the original by adding MPE support, chord memory, full MIDI control and more.
