Animusic software substitute?
 

Hi. I have a question about the Animusic videos. They combine music with animations. Their website is www.animusic.com, but you can see some of their videos on Google video or YouTube.

They use a proprietary program called Midimotion to do the animations. They talk about that here: http://www.animusic.com/company-software.html

Midimotion is not available commercially, so does anyone know of any products on the market that does the same thing? Basically, I'm looking for something that controls my animations based on the speed/beat/sound of the music. Thanks.
