Porcupines on Absynth

Gene Ward Smith described a tuning on the tuning-math list that could be considered a sort of circulating 15-note scale; since I've recently been playing with Absynth 3 and retuning old MIDI files for practice, I decided to find out what the 15-ET Mizarian Porcupine Overture would sound like in this tuning. This is really pushing the limit of what my 5-year-old system can do in real time, but I think it turned out okay. Percussion is the Edirol VSC.
