I just had published, in Soundbytes magazine (soundbytesmag.net) my review of 2CAudio's new and wonderful program Kaleidoscope. http://soundbytesmag.net/wcaudiokaleidoscope/ Kaleidoscope, as you'll see, is an amazing new take on the idea of graphic synthesis, as well as offering tuning resources not before available with that technique. I also conducted an interview with Andrew Souter, the developer of Kaleidosope, and a lovely guy he is too. Here's a link to that interview, in the same issue: http://soundbytesmag.net/andrewsouterinterview/.
Here's a look at the GUI of Kaleidoscope - which is explained in detail in the article.
And here's a 24 minute long piece I just finished with Kaleidoscope. This is about 6 different patterns made with Kaleidoscope and mixed, using about 4 or 5 different tunings. It's called "Kaleidoscope Mix Nr 2," although I know I could do better than that for a title.
