Joe Hahn aka Protman is a programmer and computer music artist based in Chicago. Primarily composing with software inspired by late 80s mod trackers like Impulse Tracker, Schism Tracker, and Renoise, he also implements the use of game controllers and other input devices with PureData to translate them into midi controllers and custom sequencers. Joe is also a proponent and often host of monthly computer music battles called "Iron Chef of Music" where contenders locally and worldwide via telecommute simultaneously spend two hours creating a new piece of music out of a single audio sample. After two hours there is an exhibition and discussion of all the track submissions where cheffers can learn about software and technique from one another. Joe is also working to open a museum and workshop in Chicago with a focus on diy/circuit-bent music hardware and software.
