Hi Eben,
Oh, please.
Hook up everything you are going to use "live" and do an "ear check"
with someone who has good ears and knows music. Forget the computer,
just dial the equalizer in with the live listener using representative
material and memorize or write down the settings.
The computer can't "hear" music, LOL.
Unless you are going to play "techno", of course. Then I don't think it
matters at all, not any of it.
