hiya, Rim--
i'm going to do some basic QA test re: crashing and snapping. see if i can reproduce the problems.
as far as the crashing: i've been using auria daily, for hours, for the past 3 weeks. at various times, auria's crashed a couple of times an hour...and always a couple of times per day. just checked analytics: in july alone, i've had 27 crashes on 10 different days. there have been 4 cpu_resorce_fatal during 3 separate days. (oddly, Analytics isn't showing any over the past 10 days, though there have been a lot.)
almost the whole time period i'm referring to has been using Audiobus3 with auria routed as output, and Bias Amp 2 as input (no middle-slot 'effect' used). also, 99.9% of auria's insert/aux fx IAA's have been FabFilters and PSPs.
ipad pro 12.9", 256gb
ios 11.4.1 (since last wednesday or thurs; the previously latest 10.?.? before that)
Focusrite iTrack Dock (no end of problems with that lovable little bugger, btw: constant crackling and loss of audio/connection).
i'll get back to you after my testing, when i know (even!) more.

p.s. i sent 2 or 3 automated bug reports yesterday. my thing about those is that i'm almost always using Airplane Mode since (even hooked up to power) my ipad pro's battery runs down like crazy with auria...so i'm rarely online during a crash. would copy/pasting the apple analytics reports of the crashes help if i sent those to you?
