Detailed Description

Program that learns a simple fully connected hidden Markov model from a FeatFile and generates chunk sequences from it.

This doesn't produce very compelling compositions because the markov assumption (that the currect chunk only depends on the previous chunk) is not at all valid for most music which has a more complex structure. Later versions will support more constrained HMM topologies that should make for more interesting compositions.

String	description = "HMMComposer uses a features file to train a simple statistical model of a song and uses it to randomly generate a new sequence of chunks. This works best when used with chunks created by the beat detector."
