I've been playing around with Ockham's music models and they're very cool. Ockham has helped me getting the Python scripts to run on my Macintosh. If you are going to use them on the Mac you must use Poser 4, as Poser 5 won't work with tkinter scripts. Also be sure to save your audio file in AIFF format instead of WAV on the Mac, just type yourfilename.aif in the WAV field. It works best when the midi file and aif file are in the Poser 4 application folder. I just got back from 2 weeks in Amsterdam and am creating an Amsterdam street scene with a calliope as the center piece so the script is making it much easier. Kudos to Ockham
