The Impro-Visor group is for using and discussing Impro-Visor (Improvisation Advisor), free software for musicians, song-writers, et al. used to create improvised solos, tunes, transcriptions, or bass lines in the form of lead sheets (chord symbols with melody).

Impro-Visor generates styled accompaniment (e.g. piano, bass, drums) automatically from chord progressions. In addition to supporting a database for storing and retrieving licks, Impro-Visor can generate new licks and full solos based on a user-modifiable grammar. Most musical information is stored as open text files. Sound output is MIDI, and playback can be exported as MIDI files.

Download the latest release from this group's Files area. Impro-Visor runs on Windows XP, VISTA, MacOSX, and Linux.
