A laser light-based control system that makes use of intelligent motion tracking camera-based technologies to allow a performed to select notes, to provide a range of values for controlling device components (such as a fader), and to select a volume or magnitude value for a selected note (or output value). The control system may be configured in some implementations with the ability to filter out other light sources to only monitor a particular light from a source using real time video processing. This allows the control system to function to track simple and also complex laser animations and beam interruptions and, in response to the results of such tracking, to generate control signals for a digital music instrument to generate an endless amount of note values and variables (e.g., volume, pitch, and so on) in a 2D space or, in some preferred embodiments, a three dimensional (3D) space.
