This is a demo mix of 5 diffent loops of music which fit perfectly to an over each other. by fading in and out the different layers one can create a change of sphere from calm to very aggressive.
Upon request I can provide the loops, which are around 40 seconds loss from each other or even split them up into more "layers" (or mix them up to less).
With this technique the music can change in a dynamic way, to follow the gameplay.
If some talented flash programmer is interested in building an "online-mixer" for this, please drop me a message.
