This group is for discussing Impro-Visor (Improvisation Advisor), free software for musicians, 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 automatically from chord progressions. In addition to supporting a database for storing and retrieving licks, it can generate new licks and full solos based on a user-modifiable grammar. Grammars can be learned from transcriptions. Music information is stored as open text files. Sound output is MIDI. Exports MIDI and MusicXML.

Impro-Visor runs on Windows XP/Vista, MacOSX, and Linux.

Impro-Visor is under development at H a r v e y M u d d C o l l e g e in California. The official home page for documentation is http://impro-visor.com/. Here is a tutorial and an example of a solo.

Download the latest release from Files>Software of this group, or from sourceforge.
Leadsheet files are available only in Files>Software, as leadsheets.zip. Expand it and replace leadsheets folder with the result.
