Compile Time Adaptive Vs Real Time Adaptive

A movie soundtrack is Compile Time Adaptive. The moving pictures, dialogue, music and sound effects are put together – compiled – to a final cut. After that, the movie shown to the public will be the same in every screening.

Computer game music needs to be Real Time Adaptive since the state of the game changes while you play, so while the music plays the state that the music somehow should adapt to changes and so the music must somehow adapt to the new state. It has to adapt in real time. The music must somehow be composed in real time.

Musifier Adative Improviser – A Real Time MIDI Music Morpher

• MAI morphs between tunes in real time, note by note, beat by beat, handling tonality, harmony, modulations, melody, rhythm, meter, tempo and timbre.
• MAI can handle any number of tunes.
• MAI is driven by a state vector defined in a Rⁿ space that is an interpretation of a source process.
• MAI can handle any changes in its state vector. The musical result however depends on the tunes used and how MAI is configured.

Paper: Musification and View

Interactive narratives like computer games pose specific problems for the musician since they involve non-deterministic storytelling. Using the terminology of the theatre we conclude a number of requirements that must be met in order to generate responsive music: The orchestra need a clear view of the stage.
