The “Supplementary Material” link on the abstract page for this article contains two freely downloadable video files. These are corrected versions of two tracks whose audio on the physical DVD is defective: MindBox and Transmissions from a Dying Planet. Please use these in place of tracks 1 and 3 on the DVD. We apologize for the errors. These files have already been corrected in the “DVD Content” article for this website. However, the tracks have been made free here for Computer Music Journal readers who have the DVD but don't have subscriber-level access to the online version of the issue.
