Cherry Audio PS-20 a Polyphonic, “Hot-Rodded” Korg MS-20 Synthesizer


Cherry Audio has introduced PS-20, a new software synthesizer. Cherry Audio PS-20 plugin is a “hot-rodded” VST version of Korg MS-20 Synthesizer. It promises everything you love about the MS-20 and plenty more.


If you are looking for a faithful hardware emulation of Korg MS-20, Korg has you covered with its mini and full-sized reboots, but if you want a “hot-rodded” plugin version, the PS-20 is the synth that will seduce you. As for sound-wise, the PS-20 sits on familiar, squelchy, screaming MS-20-style ground. Those much-loved, sometimes unpredictable filters are here, as is the modular-style patch panel. However, we are told that this has been reconfigured and simplified, with in and out patch points for all oscillators, filters and VCAs and a simplified interface. The patch panel cabling system from Cherry Audio Voltage Modular has been implemented, too. Other additions include 16 notes of polyphony, a three-layer, eight-step sequencer with CV outs, and built-in effects.


The PS-20 also features 320 presets, and offers MPE support. There’s a single-key chord memory mode, and an external signal processing section with sidechain input. It runs on PC and Mac as either an instrument or an effect, and in VST/AU/AAX formats.
