Thanks for the link, that's a fun talk :) I'm feeling philosophical,
and have no training so the following may be utter rubbish....
For me music, or any art, is a form of communication - the creator has
something in their mind, and through whatever they produce they create
an effect in the mind of the observer. It may or may not be the same
as what they saw, and sometimes it's deliberately ambiguous (abstract
art where everyone interprets it differently) but crucially it engages
and creates a connection - often an intentionally noisy or imperfect
one.
This means that for me some of the generative music we've had on the
list isn't music, in the same way a picture of the Mandlebrot set
isn't art* - that's not to say they're not interesting of course, and
it's just my definition before anyone gets too upset! The thing I'm
most interested in when it comes to overtone are the ways in which we
can create instruments which allow that creative input to shape the
results, and in particular how I can use it to build instruments with
a very tactile input capability as that's how I prefer to work.

* although this gets more ambiguous when it's a picture of a selected
part of the set, with colouration and effects applied. I'm still on
the side of 'not-art' in this case, but it's closer
