After seeing Surya Buchwald (http://www.mmmlabs.com) demoing Ableton Live to Flash at Flash on the Beach 2011, I had to find out how it was done. So I got in touch and was led to a link to download their ‘Music Event Description System’. It is a ‘Max for Live’ addon that enables Ableton Live to output OSC messages. I then recieve this data in Flosc which converts the OSC messages from UDP to XML so the data can be used in AS3 via an XML Socket. The rest is magic, and a couple of MovieClips 🙂
