Benefits of Prediction -

Temporality -

-

Proactivity -

-

Instruments are reactive. Performers are not - predict others in ensemble, results of own actions. New instruments could be proactive as well, changing mappings, or producing sounds in advance of performer/user commands.

Adaptability -

-

Interactive music framework not temporal, but music is. Deep models can introduce temporal predictions into these systems.

Musical interfaces can adapt to the needs, or expressions of the performer/user.

Generation -

Possibility for new layers of music that enhance solo performances.
