rd(prog)

Here I am furthering the concept of ring modulation in conjunction with the Karplus strong synthesis method. It's a non-interactive patch, so everything you hear is being randomly generated. The supercollider code changes the length of the delay buffers at steady regular intervals and amounts to create a rudimentary "progression" of notes, though they aren't perfect and are definitely microtonal, if you have the ear for that. The progression is happening rather slowly though, so you may have to speed up the file to hear it better. Luckily, I did that for you!
