Ha-Hi-Hun: Performance Rendering System of High Controllability
Keiji Hirata and Rumi Hiraga
Abstract:
This paper presents the design principle and algorithm of a new
performance rendering framework, and a prototype system based on the
framework.
We believe that a practical performance rendering system should be
able to refine and improve a generated performance interactively,
incrementally, and locally through direct instructions issued by a
user. In addition, the generated performance must reflect the user's
intention properly. For these purposes, we propose a new framework
called two-stage performance rendering.
The first stage translates a user's instruction into the deviations of
the onset time, duration, and amplitude of structurally important
notes. The second stage spreads the deviations over surrounding
notes.
Lastly, we introduce a performance rendering system called
``Ha-Hi-Hun'' that we are developing.
