You want to start creating audioreactive visuals? You need a simple tool to generate channels from an audio file?
As a huge user of Adobe After Effects, I spend years using a nice plugin from Trapcode, called SoundKeys. I've just recreated it inside TD.
You can define 3 zones (colored rectangles) over the music equalizer. The more the zones are filled, the more the channels are high.
It's quite simple, but VERY effective !
