Story

Loopmaster is a musical project created by a team of UC Davis EE-Emerge (EEC 105ABC) students.

Three instruments (Drumpad, Computer Vision, and Footpad) work with selections specified in a MATLAB GUI. In tandem, a BeagleBone Black and a Bela Cape are utilized to process user inputs and output different notes. The Drumpad works akin to a traditional MIDI pad, where each of the twelve buttons are mapped to notes that relate to a selection of instruments. The Computer Vision, on the other hand, maps different notes to select areas in a camera's view and outputs sound when a trigger is visible. The Footpad takes input from a user's feet and manipulates the sounds created by the Computer Vision and Drumpad.
