hi, I've just been working on some supercollider code to automatically generate notes in a shepard scale from any incoming midi events. I thought I would post the code and a sample of how it sounds in case anyone else finds it useful. The way it works is you send supercollider a stream of midi events through its midi port, and the program converts these into outgoing midi events which represent notes in a shepard scale. If you play a rising scale on a keyboard, the notes will come out as rising shepard scale notes; similarly for a falling scale. It works best if you feed it into a pure sine wave generator, but you get some interesting effects with other synths. The code and the sample mp3 are here: http://www.ganglion.me/media/ Any comments on the code are welcome. (I'm still fairly new to supercollider :) ). hope someone finds this useful,
