Impro-Visor 6.0

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.

v6.0 [Jun 22, 2014]
- Now the pitch of the note is displayed to the left of the arrow-head note cursor. This may be turned off in the View menu.
- There is an alternate cursor in the shape of note head. The note head will have a line through it if the note is on a line, and no line if the note is on a space.
- The Style/Section editor has been changed to allow greater flexiblity.
- Sections may be added and removed on the staff by using a shift-click.
- There is an option in the View menu to display Major 7 chords using a delta, and minor 7 flat 5 chords using a phi symbol, as is done in some leadsheets such as Aebersold and the Real Book.
- There is a virtual keyboard for entering notes on the screen. It has an advising option that indicates whether a note is a chord tone or color tone, as well as some other options. This is opened as Advising Keyboard from the Utilities menu or with control-shift-K.
- There is now an option within Import MIDI Tracks from File to infer chords. Now the Style Extractor does not require a leadsheet file to specify chords; extraction is done only form MIDI files.
- There are some added styles that were extracted from MIDI files generated by ChordPulse.
- The grammar formalism contains some new constructs, including the ability to specify relative pitches (rather than just abstract notes), and other built-ins, such as for generating George Garzone's triadic melodies.
- There is also a grammar for Jerry Bergonzi's method of improvisation, described in his book Melodic Structures.
- Now a new leadsheet can be constructed from a roadmap.
- The roadmap analysis algorithm has been changed to use harmonic tempo.
- Now the Improv button will start improvisation over the selection and loop continuously, until the button is toggled off.
- There is a preliminary facility for audio input, however it requires co-installation of SuperCollider with the Tartini plug-in.
- Audio is converted to MIDI, which Impro-Visor can input in real-time.
