I believe, in this new update, you can load any custom profile you want, from the entire AutoEQ database (There is a VSX profile in that database). But with regard to VSX, VSX has had solid amount of different series of hardware, so you'd want to know which series was captured to match it to yours. There is a way you could reverse engineer the exact curve specific to your series, but I don't recall, at the moment, how that's done. But it's not terribly difficult to do.
