So then I use the X-axis of the Soundplane to sweep through the timeline of Mario's universe. Not only that, but the Soundplane is multitouch, so I use a second finger to specify start and endpoints in a playback loop. This is similar to the way samplers and granular synths work, but for recordings of the entire memory state of the NES rather than audio data. Conceptually, it is like Super Mario meets Groundhog Day. Mario's universe computer / time machine gets caught in hellish loops.
