SoundHelix is a free, versatile and flexible Java framework for composing and playing algorithmic Random Music based on constrained random generation (CRG).

Features:

produces enjoyable non-esoteric algorithmic random music
can generate full songs within a couple of milliseconds
fully configurable using XML
can be used
- as a standalone Java application
- as a JNLP-based applet
- as a WebPage-based applet
- within third-party Java software (e.g., as in-game music) via the SoundHelix API

- can remote-control any number of MIDI devices in parallel with up to 16 MIDI channels each
- supports any number of synchronized LFOs for slowly changing MIDI parameters (modulation wheel, pitch bend, etc.)
- supports sending MIDI timing ticks to selected MIDI devices (for timed effects like echo)
- supports configurable non-uniform timing (groove patterns)
- supports milli-BPM playing speed resolution
can be extended easily by providing additional implementations for the defined Interfaces
