A tutorial on the basics of Houdini chops, and then two examples of music driven animation.
In the second part we set up a particle network that will be driven by music being brought in through CHOPs.
How to import music into CHOPS, using pass filters, envelope and trigger to get the curves we want to drive animation. Using pitch to split out different frequency components and then use these to drive the colour of the particles.
**Two mistakes crept into this video. One is that Houdini does in fact recognise MP3 files (it just seems to have had a problem with the particular file I used). The other is that there is bit missed from the video where I add a chop function to the y component of the tranform sop that moves the ball, to bring in the height channel from chops. Its there to see in the project file, however. **
