They're almost like hardcore l33t emoticons if you turn your head 90º.
Think I read that they were from an Indigo (it was unclear as to whether it was an Indigo 1 or 2), and that they routed some parameters to the soft knobs to "optimise it" for the TI.
Thinking about it, I doubt they'd start changing the actual sounds themselves as Sasha/Jamieson probably wouldn't be happy about it!

A ribbon-controller or XY-Pad might be nice, too, please! Thanks!
