1. The content-based scenario is the profile of spectral centroid and roughness extracted from the soundtrack of a musicless movie scene. It is applied to a memory constituted by the piece Atmosphères (Ligeti) analyzed with the same couple of audio descriptors. The generated sequence replaces the original soundtrack.

  2. Additional material for: Nika Jérôme, Bouche Dimitri, Bresson Jean, Chemillier Marc, Assayag Gérard, "Guided improvisation as dynamic calls to an offline model", Sound and Music Computing conference SMC 2015, Maynooth, 2015.
    (https://hal.archives-ouvertes.fr/hal-01184642/document)

    Offline simulation behind the GUI: focus on the "improvisation handler" embedding the offline "scenario/memory" generation model in a reactive framework.

  3. First technical experiments with the composer-improviser Michelle Agnès.
    Alphabet for the scenario: (loudness, brightness, playing mode).
    The system starts with an empty memory and reinjects the live audio material matching the descriptor profiles imposed by the scenario which is composed in such a way that the machine improvisation alternates between counterpoint and extension of the musical gesture.

  5. Example of video improvisation (realized by Georges Bloch) using the music improvisation system ImproteK. The system can be chained to a video player and improvise by re-injecting offline or online video, transformed and reorganized to match a given scenario.

    In this example the "scenario" provided to the system is the harmonic progression of "The Man I Love", and its memory is constituted by several videos:
    - Lisa della Casa singing "Mi tradi quell'alma ingrata", Don Giovanni, Mozart,
    - Edith Piaf singing "Mon Dieu",
    - Billie Holiday singing "The Man I Love",
    - Hervé Sellin playing "The Man I Love".
