ArtSong is a large and highly configurable musical building-block based algorithmic music composition framework designed for composers, experimental musicians, and advanced music hobbyists. Designed as a general-purpose composition framework, ArtSong is 'intended' to be devoid of any particular musical style; an electronic-procedural manuscript paper that you can apply to any specific composition problem.
Key Features of ArtSong 6:
-Scripting: a complete script development and runtime environment for both Pascal and Basic scripts with syntax-sensitive source-code editors (keyword highlighting), integrated debugging, and a large library of built-in objects and functions is included. ArtSong's scripting capabilities offer a powerful general-purpose solution for composition, analysis, or editing.
-Over 30 algorithm plugins including 8 distribution functions, chaos attractors, image to music, text to music, meter, chord progression generaters,
-Controller components supporting any MIDI channel-voice message can be associated with specific tracks,
-Unlimited tracks and algorithms per project,
-Setup and directly compose an entire score at once or compose in real-time while playing,
-Tonal compositions can set a pitch-generation probability for each individual pitch-class for adding varying degrees of chromaticity to tonal compositions.
-Scale and Chord resources can be defined and applied as defined over the full 1- to 10-octave MIDI pitch range. Chords defined within a 1-octave range will be repeated each octave, chords defined over a 2-octave range will be applied every two octaves, etc.
-A Single-Note Editor has been added for adding-editing of individual note events.
-Multiple Time Signatures
-Multilevel Undo/Redo
-Save projects as MIDI, ArtSong Projects, or simple CSound score files,
-Automatic conversion of MIDI files to ArtSong projects,
-Build custom libraries of data patterns, presets, and project templates for reuse .
