it's continuing to behave poorly, but it really has to be a registry issue. i'm going to try a driver reinstall, but if that doesn't work i'll have to back up and do it again - this time inserting a wipe before the reboot, to prevent the install from completing.
on a clean sweep install with everything the way it was saved a few weeks ago, which means that the streaming proxy bit & clock are broken, it no longer bleeds. it's stable on the out. but, the out is missing a layer at the high end. it sounds like less an eq dive and more like a straight low pass, but i'm suspecting it's more along the lines of that a part of the stream is broken. it's pretty high - around 10 Khz or so. and, if you'll recall, this was the basic problem i noticed in the first place, which had me mixing higher than i wanted.
but, here's an interesting fact: i've pointed out before that a firmware flash resolves the issue. and, that's what is continuing to happen, but only until i reboot the device. it's quite strange.
in theory, i could just flash the firmware every time i turn the device on. but, that's kind of scary. if the power goes out when it's flashing, i could brick the device. and, if the issue is that the firmware is instantly corrupting, i want to think about replacing it.
