We have been developing and honing a real-time audio/visual control system that allows for simultaneous control of music and visuals. 
A hard-wired ethernet network is created between two laptops, then a MIDI network is created to send triggers from Ableton Live to Resolume Arena 5.
This has become the performance setup for Tetrafyre and has been adapted to the needs of other artists like Alluxe and Oseya.
