Live-Sequencer does the following: An editor shows a textual description of music (like Haskore), an interpreter computes and emits a stream of MIDI events via ALSA. While doing so it highlights active terms and shows the result of the term reductions. The nice thing is, that the user can change the program while it is performed. Additionally modules can be altered via a web interface. This way several people can take part in the composition. However they need to have video and audio access to the running sequencer in order to see and hear how their parts fit into the overall composition.

We address two applications:

  • interactive multi-user programmed music composition
  • education of how functional programs are interpreted
