Raphael Radna has released a virtual synthesizer that implements and extends the Dynamic Stochastic Synthesis (DSS) algorithm invented by Iannis Xenakis: Xenos.

Programmed in C++ with the JUCE framework, Xenos is open-source, cross-platform, and can be built in a number of plug-in formats.

Xenos features

  • Authentic DSS engine.
  • Xenharmonic pitch quantizer.
  • Custom scale import in the Scala format.
  • Ten stochastic distributions with up to two parameters each.
  • First- and second-order random walks.
  • Variable number of segments per wave cycle.
  • Variable amplitude envelope.
  • Polyphonic (64 voices by default).
  • MIDI implementation (notes, sustain, pitch bend).
  • External MIDI controller assignment.
  • Parameter automation.
  • Simple and streamlined interface.

Binaries of Xenos are available to download for Windows and Mac (VST3, AU), and the synth can also be built from source.
