I met with an electrical engineering professor today

[Swimming Bird]

So I met with this EE guy today. I knew he was into alternate tunings and engineering related music things, but the programs he was working on -- that I may well be working on next semester -- seem to be wholly original and awesome.

And thanks to our talk today, he's going to adapt them for live usage. Of course if these ever make it to market, you'll all be the first to know.

I don't want to go into detail, but he's messing with timbre by changing a note's secondary frequencies. This is being done the hard/direct way, unlike some Moog stuff which lets you sort of experiment.

Oh, and he's not looking at changing timbre of one instrument to another so much as doing the Michael Manring thing and changing timbre through alternate tunings, except he's doing it digitally.

So kinda like pitch shifting only the harmonics?

[Sir Edward V]

sounds interesting

I want to know more.

Has he published any papers on this? (I have access to IEEE and AES publications if it was in one of those)

It sounds pretty interesting. I can think of some brute force ways to do this, but it wouldn't be pretty. I'd love to see what he's doing.

Search for Sethares. He wrote the program this summer, so I doubt anything is published yet. I've taken a look at the code, and some is brute forced, but a lot is extremely elegant.

Yeah, it's sort of pitch shifting just the harmonics.

First result on Google for Setharas:

Some general Info on him.
