--- NEW FILE: harmonizer.c --- /* harmonizer: this external build voicing from a chord to another. takes n voices (midi) as input you can set the current chord you can ask for next note of each voice to get to a target chord

usefull to create chorals

voicing is built using traditional GA (not co-evolving GA)

voicing rules are hardcoded and are: - no parallel 8ths nor 5ths - better no hidden 8ths nor 5ths - better if uniform voice spacing (except for the bass) - better if little intervals - no all voices same direction - no voices outside limits - better complete chords

TODO: would be nice to be able so set some rule at runtime or at least set the importance of rules in realtime..

--- NEW FILE: README.txt --- frankenstein set of externals

authors: dmorelli: www.davidemorelli.it pland: www.davidcasal.com with the help of vatic

last update: 14-10-2005

------------------- what is this?

this is an attempt to build an intelligent system for realtime improvisation, a system that follows a human player and proposes rhythm, melody, chords sequences, formal structure. it learns the style in realtime. it uses various AI techniques: GA, searchs, ANN (maybe)

description of files:

chord_melo.c a GA melody generator. it takes a melody as input and evolves it over time. uses co-evolutionary techniques (Todd)

chords_memory.c it is a directional graph which implements a memory of the played chords sequences, you can train it... and once trained you can ask questions like: in C major, from a D minor 7h where did I go most if the times? or in C major, from a D minor 7h build a chord sequence to bring me in D major in 4 steps using the chords sequences I used most

harmonizer.c a GA external that build choir voicing for 5 voices: you pass it the midi value of each voice, starting chord, next chord and it outputs a list with the midi values of each voice. avoids hidden 8ves and 5ths.

folders:

doc/ implementation documents, notes, logs, ideas, etc.. patches/ example patches, help patches, some used in performances, etc.. aima/ python patches not yes used but interesting for agents ruby/ gridflow patches not yet used old/ old not used code test/ testing code, not to be used backup/ previous versions

TODO:

gluer/solderer an external that takes the input of two or more chord_melody, a chord sequence and glues the melody statemets together to build a long complete melody.

form_manager an external that manages the form and structure of the piece: decide which melody statement to use, the chord sequence to ask for, etc..

various objects to detect played notes

diatonic_melody.c same as chord_melody but without chord reference, only scale used (for post-tonal music non based on chords)

chromatic_melo.c same as diatonic_melo but without any reference (for atonal music)
