Xenos

Dynamic Stochastic Synthesis

Xenos implements and extends the DSS algorithm invented by Iannis Xenakis. Programmed in C++ with the JUCE framework, it is open-source, cross-platform, and available in a number of plug‑in formats.

Xenharmonic & microtonal ready

Explore beyond 12‑TET with the built‑in xenharmonic pitch quantizer and import custom scales in the Scala format. Xenos embraces just intonation and alternative tunings effortlessly.

Stochastic distributions & random walks

Choose from ten stochastic distributions with up to two parameters each, plus first‑ and second‑order random walks. Shape waveforms with variable segments per cycle and amplitude envelopes.

Polyphonic & expressive

128 voices by default, full MIDI implementation (notes, sustain, pitch bend), and external controller assignment. Parameter automation is fully supported.

Same synth, new features

We've totally reworked Xenos to add premium features that go beyond the original open source version.

Use cases

• Exploring stochastic textures and evolving soundscapes
• Microtonal composition and xenharmonic experimentation
• Algorithmic sound design for film, games, and electronic music
• Research and education in computer music and acoustics
• Building custom patches with random walk modulation
• Integrating with modular and hybrid setups via MIDI
• Creating unique, non‑repeating rhythmic and tonal structures
