PS-20 is an ultra-realistic, polyphonic, hot-rodded tribute to Korg's renowned MS-20. First and foremost, PS-20's dual highpass/lowpass filters super accurately recreate the MS-20's famous raunchy sound in all of its squelchy, screaming glory. In addition to its unique filters, the MS-20’s other signature feature is its modular-style patch panel. We’ve reconfigured the patch panel from the original instrument, adding many desired in and out patch points for all oscillators, filters, and VCAs, correcting the confusing terminology of the original, and throwing in a few extras that greatly expand its usability.

Every part of the instrument has been "souped up" with killer features, including 16-note polyphony, a unique three-layer, eight-step sequencer with flexible CV outs, and integrated effects, including a beastly distortion, modulation echo with stereo spread, and a lush digital reverb with fantastic spring and plate emulations.

The PS-20 truly is one of the most quirky and unique instruments we’ve released. Between its sometimes unpredictable filter behavior, and the tremendous flexibility of its patch panel and sequencer, the possibilities are endless, and the creative "happy accident" quotient of PS-20 is simply off the charts!

Analogue Class

Only had this synth for a little, and yet the sound creation possible is incredible, with this and the 8 Voice, and at the price too. Well done Cherry Audio. Mono and Poly modes, rich filters and power oscillators make this a stand out synth.

Just what I'd hoped for

I bought an MS-20 in 1978. Your revise addressed all the missing elements I'd ever wanted. Congratulations!

I have hundreds of softsynths, including Halion 6 , Ober 8, and Arturia V Collection 6, Pigments, Loom etc, and find the PS-20 has the most wonderful & all-round sounds of them all. PS-20 has everything I want in a synth, and more.
Amazingly well done Cherry Audio folks!

Very close, great enhancements

My old and trusty genuine Korg MS-20 is sitting next to me on the table... I used to connect it to my DAW via a MIDI2CV-Box. But it's not that reliable any more, the knobs are crackling and the oscillators drifting... so for everyday sound design, I find the PS-20 a great substitute. Of course you cannot expect every nuance that gives the "old beast" its character, but this not the point anyway. For me, at least.

The PS-20 hast its own character and sounds great. The enhancements over the original are very clever and makes the plugin very versatile in my projects. Also, it is polyphonic and it's a bargain! You cannot make a mistake when purchasing this.

Soft synth game changer!

Absolutely incredible soft synth - the most analogue sounding plugin I have used. If I could give 6 stars I would be a happy man. Incredible.

Great value!

I picked up the PS-20 via one of Plugin Boutique's sales for Beat Magazine February 2024 issue as part of a discount package.

Not only was this an incredible deal (value partnerships kick *** BTW... the synth plugin was rather surprising in its versatility.

Not only were the included Presets and Preset libraries 'usable' for many music genres... the plugin itself was-is a joy to work with.

In a number of ways, I prefer the PS-20 to the original Korg hardware or even the current official Korg VST.

I commend the entire Cherry Audio team for such a fine release!
