I've used it for the basis of generative software I've been working on. The output is quite musical. It generates scales, chords, chord progressions, accompaniment, melodies. I've also adapted the techniques to generate regroove files.
The link below is a dump of 100 different runs. You can bring them into reason and replace the devices and play around. Find a nice 4/8.16 bar section and loop it. Find a few more sections and chop them up. Add some beats. Add some regroove.
