Below is a screenshot of the interface to the patch.  The patch set itself is presently available as a beta by request.

AmbiGrainer is a high quality granulation engine, with sub-block grain timings, capable of producing some very smooth sounds. Grains may be individually panned in 3rd order Ambisonics (with per-grain order specification). Grains may also be specified directly by an external algorithm, or at a meta-level using the provided GUI. A nice feature is the creation of an Ambisonic grain cloud of grains at randomised directions.  The system can run many thousands of grains per second, with 80 simultaneous voices running easily on a 2007 MacBook Pro.

Dans une zone ponctuée de traces lumineuses au sol, le visiteur muni d’un casque audio est invité à explorer librement l’espace. Au cours de la trajectoire, des sources sonores ponctuelles s’activent lorsqu’on les traverse. La musique est écrite, c’est à dire structurée dans le temps, mais seule la déambulation du spectateur l’actualise, la révèle. Libre à chacun d’inventer son parcours : se laisser porter par la musique, se rapprocher des sources guidé par l’appel de la lumiére, en expérimenter les limites spatiales ou temporelles…

English translation by myself:

In an area punctuated by zones of light on the ground, the visitor, equipped with headphones, is invited to freely explore the space. Sound sources are activated as the listener crosses the zones of light. The music is “written” - that is to say structured in time - but it is only actualised and revealed by the movement of the spectator. The listener is free to make their own way through the piece - to be carried by the music, or guided by the light zones towards individual sounds - to experiment with its spatial and temporal limits.
