**Java source available
**Uses objects and hierarchy heavily - can Max handle this sort of computation?
**Uses expert system decision making
**Uses weighted probabilities

*"Experiments in Musical Intellegence" - David Cope, 1981-2006 <ref>http://arts.ucsc.edu/faculty/cope/experiments.htm</ref>
**Attempts to replicate composers' styles by mimicing rhythmic patterns
**Utilizes LISP heavily
**Supposedly artificially intelligent - sounds pretty much like identical rhythmic patterns used with different notes
**Clearly not as random as the goal application

==My Design==
*Development
**Cycling '74's Max
*Data Storage
**Single Note
***Start time
***Expected duration/end time
***Instrument
**Phrase / riff
***List of notes
***Used as a guideline - possibly have the ability to randomize or interact with other instruments' lines
***Possibly generate a bunch of phrases before the song is "written"
***Possibly don't tie phrases to "real notes" - instead use "relative notes" so phrases can be applied to whatever key the song is in when the phrase is used
**Phrase Order
***Have a way to organize the song
***For instance, maybe a chorus happens ever 8 bars in a particular song. The song ends in 48 bars. There's a beginning phrase and an ending phrase that need to be played on time
*Process Flow

 ****Calculate by previous note and placement in measure - ex. one triplet is most likely to be followed by 2 other triplets
 ****Or - Random using natural note event probabilities (see [[Suff:Progs]])
 ***Pitch
 ****Recalculate probabilities each time a note is played - Base on proper music theory
