Beyond Physical Modeling

“Plasmonic sounds like nothing you’ve heard before” – Marty Cutler, Synth and Software

Plasmonic captures the complex acoustic resonances of Physical Modeling, expands on it with more familiar elements of Subtractive Synthesis, and adds a few unique twists.

From plucked strings with an acoustic presence, to vast imaginary soundscapes, to gnarly leads and complex rhythmic textures, Plasmonic  will go wherever your imagination takes it.

Exceptional Factory Presets

“I rarely write letters to developers, but I have to say: Plasmonic is the greatest-sounding synth I own (and I own EVERYTHING).”  -Stewart Winter

Plasmonic’s included sounds cover a very wide palette and are designed for maximum playability. 

All factory presets use all 8 macro controllers to provide easy tweaking and expression; every preset is like an instrument of its own.

“The Macros work so well with my Panorama T6 controls. I spent so much time working with the first new preset, it’s going to take me years to enjoy them all!” – Chris ‘resequencer’ Steller – Synthesist /Product Specialist / Trainer

Designed for MPE

“The most MPE-friendly of my synths, and that includes the Roli ones.” – David Heal

It’s easy to configure Plasmonic to work with your MPE controller! And all of Plasmonic’s factory presets are MPE-ready.

MPE Slide and Pressure are an integral part of the modulation framework, and they can control almost any parameter for unlimited expressive control.

“I’ve just spent a whole night playing presets in MPE mode with my Linnstrument and being astounded by the wondrous sound(scape)s of what has rapidly become, by far, my favourite virtual instrument. As dawn approaches, my drooping head says “get some sleep” … but all I want to do is go on Plasmonically experimenting!” – Rob Stuart

Deep Modulation​

“Your Modulation page makes programming complex sounds a true pleasure, not to mention fast and furious. “  -Eric Young

Plasmonic makes it easy to modulate almost any parameter with any combination of a wide array of very flexible modulators.

The Modulation Assignments Panel is always one click away, and provides precise control over the way each parameter is modulated.

Plasmonic’s modulation potential opens new horizons for responsive, expressive sounds with an unprecedented level of sonic detail.

Unique Effects

“If I were a millionaire and commissioned someone to make a custom synth for me it would have turned out just like this.  I know I am gushing- but this thing is so wonderful. “  – Christopher Gould

Plasmonic’s effects have as much creative potential as the rest of the instrument. 

Self-oscillating delay effects range from transparent spaces to chaotic noise-scapes. The unique Sympathetic effect adds harmonic resonances that respond dynamically to audio input.

All effect parameters are integrated in the modulation framework, making the effects section an integral and expressive part of the sound.


Factory Presets

  • MTS-ESP support
  • Import of scl and tun files

Four Audio Sources

  • 2 wavetable oscillators with dynamic wave transformations
  • A special impulse generator for making the resonator ring
  • A noise generator with its own resonant lowpass filter

Two Interacting Filters

System Requirements

  • Windows (64-bit only): 8 and higher. 
  • macOS10.12 (Sierra) to 14 (Sonoma). Native Apple Silicon support.
  • GarageBand is not supported.


  • macOS: Standalone, Audio Unit, VST3
  • Windows: Standalone, VST3

Attention VST Users! Plasmonic is only available in VST3 and AU formats, so please make sure your DAW supports VST3. This is because Steinberg is no longer licensing VST2 to new developers.


With one license you can install Plasmonic on up to 3 machines, using only one machine at a time.

Plasmonic requires internet access during activation, once activation is successful it no longer needs internet access. There is no support for offline activation.
