Max/MSP Canon Patch
The Max/MSP patch Download file has 4 looping recorders and you can add feedback and pitch control, so it allows you to make a little canon. It's based on Noah's "Lidell2" patch, which you can find on his blog. What you see in this image is not quite what you'd download here, it's a messier version. I have a cleaner with which I'll update this download when I manage to fix it, but it's broken right now.
