Ableton + Processing Visuals
Processing synced to Ableton Live for real time generated visuals.
This briefly was my setup at Xorko festival in Arminou.
Today I will show you how to make super-awesome-real-time-rendered-visuals to accompany your controllerism set!
Of course there are many many many ways to do this, some may be easier ( take a look at vvvv or max msp with jitter) but we will be looking at Processing, which requires some very basic Java programming. But the same principles can be applied everywhere.
