Ha-Hi-Hun plays Chopin's Etude
Keiji Hirata, Rumi Hiraga · 2003
A new framework called two-stage performance rendering was proposed in order to make it realize incremental, interactive, and local rendering through direct instructions issued by a user. 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. Ha-Hi-Hun is a prototype performance rendering system having the framework. 1
