About

The project uses a fixed-step gravitational simulation to generate notes, rhythms, durations, and control data. The same initial state and transport timeline produce the same MIDI output.

The simulation engine is shared by the Logic Audio Unit MIDI effect, VST3 instrument, and standalone CoreMIDI application. It includes 24 factory systems and portable .3bs configuration files.
