"basically u can grab audio files (preferably MP3 because wav samples will cause a bit of a hang due to processing) and drop it like how you would drop the "coin-like" controllers in the Audiopad... the out look of it is almost the same with the path of circular rotating stripe turning... and two blue circles that is L/R output... so you drag any other cirles (sound files) with rotating aura close to either one it will be louder left or right... hard to explain it.
I have used it for live improvisations basically to make my sounds travel more organically with control of the mouse. You remove files by doing a ctrl+x; to add files just drag and drop.."
BTW, check out this post on Audiopad for video that will give you an idea of how this works.
