Thanks for the clarification on my questions, it is much appreciated. As you touched on briefly, a lot of these requests (with the exception of micro pitch in the main feedback loop), would require a fair bit of work both in DSP and in the GUI layout, and as such might bloat the plug-in a bit. I think generating and controlling ringing modes might be a cool separate product, or something we expand on in the future, but of course I can't make any promises 🙂
Unfortunately, the links you posted for the audio clips don't appear to work (I'm guessing the aren't set publicly on dropbox).
