I now have a shiny, brand-new copy of Augustus Loop, thanks to the kind folks over at Expert Sleepers. It's a really great software looper, with lots of tweakable parameters and realtime performance control.
The thing is, it's an Audio Unit plugin and doesn't work with Cubase, which I use. However, thanks to Soundflower and RAX, I have been able to integrate it with Cubase. It took me all day to figure out how to get it working, and this little piece is the result of that work. I'm too tired to do any more.
