this is a port of a pd patch by martin brinkmann that in turn is a port of a reaktor ensemble by lazyfish. i wrote this sc patch in 2006 and recently revisited the code, added a preset system and made it run under the current supercollider version 3.4.
though there are a lot of things that could be improved. the graphical interface is particularly rough and ugly.
attached is the code and a short mp3 with example sounds.
