The ACCompanion v0.1: An Expressive Accompaniment System
This work addresses the need for more realistic and responsive musical accompaniment systems for musicians and performers, though it appears incremental as it builds on existing models like the Basis-Mixer.
The authors tackled the problem of creating an expressive accompaniment system for MIDI input by developing the ACCompanion, which uses a probabilistic monophonic score follower and a linear Gaussian model for tempo updates, resulting in a system that enables expressive dynamics, timing, and articulation.
In this paper we present a preliminary version of the ACCompanion, an expressive accompaniment system for MIDI input. The system uses a probabilistic monophonic score follower to track the position of the soloist in the score, and a linear Gaussian model to compute tempo updates. The expressiveness of the system is powered by the Basis-Mixer, a state-of-the-art computational model of expressive music performance. The system allows for expressive dynamics, timing and articulation.
