Hi David, hi list,

I'm not using PD myself, but i used  Orm Finnendahls old 68k-only 
Markov object (recently ported to PD)  for a max patch controlling 2 
dot matrix printers. Not exactly microsound, but still pretty noisy;) 
The markov object would parse an existing dialog on a letter by letter 
(i.e. ascii-)level, 4th or 5th order IIRC, and generate ever changing 
new text. I have no idea of the math going on inside (I'm very grateful 
for those black boxes), but once I understood how to work with it I 
found it relatively intuitive to use: you 'teach' it with a stream of 
data, and then it outputs something similar, but not quite the same and 
never repeating. Not sure if this counts as AI though. I never really 
used it to produce sound, but feeding it with note data / midi files 
gave some interesting auto-variation melodies.

There's a markov object for pre-OSX Max by Nao Tokui that uses Bachs 
"Jesu, Joy of Men's Desires" in the help file;)

best, g.
