The MS Synth Experience, Supercharged

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! 


What musicians are saying:

Ambitious, revealing, daring, and musical. The original Korg team did a magnificent job with the original Korg MS20, inspiring whole landscapes of sound in every genre. The Cherry Audio team have expanded upon the original design and brought it into the future.

The PS-20 is a bona fide 'spiritual reimagining' from a parallel universe, setting right what went wrong, and providing fresh modulation and effects possibilities to beef up the badassery. The PS-20 really shines with its full-on polyphony, especially when clean-crisp tones are transformed into cranked-up distorted mayhem.

PS-20 is incredible! User friendly with endless possibilities - I am amazed by this product and will use it in the studio as well as on stage. Cherry Audio did it again!

This thing wheezes, screams, and has a vibe unlike any other virtual synth I’ve laid my fingers upon! It’s UGLY and beautiful! it’s PHAT and thin in a very funky way! Just like your other VI’s this sounds like hardware, not some lame attempt at recreating a classic synth. WELL DONE!

Loving the PS-20! It's not everyday that you find a new plugin that does so many things so well. I started off using it for its deep bass sounds, but then discovered how good it was for pads and other polyphonic sounds. Most recently I've been using it to create soundscapes using the sequencer and the effects. It looks like an MS-20 but there's so much more going on here.

It's great to see an under-appreciated vintage synth get a makeover. PS-20 is faithful to the original sound and panel layout while adding some great new features - much more comprehensive patching, a handy step sequencer, some basic effects, transport sync, and of course polyphony. I'm impressed!

I had been thinking about putting together some components for the Eurorack hardware modular experience, but after playing with the PS-20 and integrating my nakedboards MIDI controllers, I’ve decided to save the $10K and put it toward a trip to Europe instead!
