From the developer:
Impro-Visor is a music notation program for jazz musicians. The main objective of this program is to improve understanding of solo construction and tune chord changes. Since rhythm-section (e.g. piano, bass, drums) accompaniment is automatically generated from chords, Impro-Visor can be used as a play-along device.
