AudioMulch is software built for live performance, audio processing, sound design and music composition. It has been used by the likes of Girl Talk and Pete Townsend (you know, from The Who!). I worked for Ross Bencina to help with the port of AudioMulch 2.0 to OS X back in 2008 (-ish). I wrote a bunch of the native OS X code (CoreMidi, persistence settings store, VST hosting, etc.), primarily in C++ but also some Objective-C, there could have even been some Python in there for the Scons scripts, it was a long time ago now!
