The Alphatrack by Frontier is a little midi control surface or in a very simple term a very small mixer. It's made to control the grafical audio or midi channels and its parameters like effects of programs like garageband, protools, sonar and so on. This is very comfortable because instead of working with a mouse or key commands to make a audio signal like music louder or more silent you just pull a fader on the alphatrack up or down. It's hands on control in a physical way. I hope you get the idea. Kind regards Ben
