We introduce ImproteK, a system integrating a rhythmic framework and an underlying harmonic structure in a context of musical improvisation. In the filiation of the improvisation software OMax, it is built on the factor oracle structure to take advantage of the particularly relevant and rich characteristics of this automaton in a musical environment. Moreover, it can adapt to a regular beat and produce improvisations following a given chord progression. ImproteK is conceived as an interactive instrument dedicated to performance: its improvisations are based on the style modeling performed on live playing or on an offline corpus. Combined with pattern reuse techniques, this modeling expands on harmonization and arrangement in a harmonic interaction module.
