Hmm, couple of corrections: I'm actually exporting audio to the same drive my Data is stored on (I:\ - internal SATA 7200rpm). I may have found my problem
F:\ drive is also an internal 7200rpm SATA drive with BFD folders. Apparently I've bjorked my BFD install so many times that I've forgotten which drive was supposed to do what
(copies a bunch of files from I:\ to F:\)
Ok, so now that I've got all my BFD stuff separated from my export stuff AND my system, time to see if I still get issues.
Anyway, even with that setup, my dropouts were largely limited to one cymbal: the Zildjian 16Z Custom Medium Crash. Every so often I get faint dropouts in my hi-hat and snare, but 90% of the time, it's that one Zildjian. I also get distortion in my OH, Amb3, and Room mics unless I set the snare and kick routing to those mics in the kit view to 0.
