An additive synth you draw by hand.

Draw the harmonics of your patch directly, paint spectrally shaped noise, or drag in an audio sample or an image and it resynthesizes it into a playable instrument. The engine is digital, but most of it is analog modeled, so it has some warmth and movement to it.

What it is

Additive synthesis, with a subtractive engine too.

The Spectral Synthesizer is an additive spectral synth. Instead of starting with oscillators and a filter and subtracting, you build the sound up on the Spectral Canvas: draw the harmonics of your patch directly, paint spectrally shaped noise, and sculpt the timbre with a brush.

You can also drag in audio samples or image files and it resynthesizes them into playable, evolving instruments. There is a standard subtractive engine in there too for more traditional sounds. The engine is digital, but most of its parts are analog modeled, so you get some tape warble, pitch drift and saturation baked into the sound.

  • Drag and drop resynthesis in real time.
  • The analog side: pitch drift and tape saturation.
  • Everything is on one screen. No menu diving.

At a glance

What is under the hood.

Universal resynthesis

Clone the timbral DNA of any audio file or image. Drop in a sample or a photograph and get a playable instrument in seconds.

Generative sound design

When you want a starting point, one-click Pattern and Sacred Geometry generators build complex spectrograms for you.

The Spectral Canvas

Draw harmonics, paint spectrally shaped noise, and erase with a brush. There is a proper undo, so you can experiment.

Analog character

More than warmth: pitch drift, tape warble, saturated delay feedback, even simulated tape dropouts.

Classic harmonic voicing

Sculpt the core timbre by switching between All, Even, Odd, and Inharmonic modes.
