@nprofile1q... This does make me wonder... This is presumably audio processing/mixing software, right? How much of the gigs of memory is used by doing this?

How much faster/lighter would the software be if these were video gamey dynamic knobs/dials? Or even 3d knobs rendered using the same graphics space for textured 3d uv maps instead?

It's certainly a special way to do the interface, I suppose. I guess being "exactly the same" was really important for the software users.
