Interesting study. But conventional vis-a-vis all the unexplored timbre-space out there. I'm wondering if it'll be modifiable to 'morph' between two timbres in finite steps (by mod'ing partials). So you could play on any of those steps, or float around, or gliss along them.

Flute+tuba => fluba. Fluba+violin => fluvioluba. And so on. (Harry Partch also wonders.)
