The ColorDex DJ system: a new interface for live music mixing

This paper describes the design and implementation of a new interface prototype for live music mixing. The ColorDex system employs a completely new operational metaphor which allows the mix DJ to prepare up to six tracks at once, and perform mixes between up to three of those at a time. The basic premises of the design are: 1) Build a performance tool that multiplies the possible choices a DJ has in respect in how and when tracks are prepared and mixed; 2) Design the system in such a way that the tool does not overload the performer with unnecessary complexity, and 3) Make use of novel technology to make the performance of live music mixing more engaging for both the performer and the audience. The core components of the system are: A software program to load, visualize and playback digitally encoded tracks; the HDDJ device (built chiefly out of a repurposed hard disk drive), which provides tactile manipulation of the playback speed and position of tracks; and the Cubic Crossfader, a wireless sensor cube that controls of the volume of individual tracks, and allows the DJ to mix these in interesting ways.
