I've been banging around on another pd abstraction that's turning into a nice sound generation tool. As with most pd interfaces, it's not much to look at, but it's being called "caradisio" and it looks something like this:
I'm posting prematurely and apologize for not having sample audio yet.
Although the number of controls is smallish, this thing can sound like an epileptic seizure in a field of cold mud, rusted metal, and broken glass. The concept is pretty straightforward: Take a wavetable synth and evolve the waveform in nasty ways (in this case, pin, lin, and sin). With some reverb, it starts to sound nice and thick...and sometimes there are secret eerie voices that creep in from the muck.
When I finish and clean it up more, I'll post it to my pd page.
(Aside: I think that if pd ever gets antialiasing [for both fonts and controls] and gets more/enhanced drawing primitives for data structures [hello...arc or circle!], we could start to generate some decent interfaces.)
Oh, and I've recently started associating with the newly started dorkbot pdx collective. It's still in its infancy, but the people seem smart and interesting, and I'm sure we can turn the group into something wonderful.
