I upgraded to the November update this evening and started to try and track some guitars. I can't use the 1810c at any of the following settings without pops and dropouts:
Btw, the mentioned settings were the only one I tried. Prior to this upgrade things were fine. The PC meter in cubase shows that it sporadically gets pretty high usage, but I have a very powerful (2019 i7 16gb of ram, liquid cooling, high end graphics card, etc.)
The PC is also my daily driver and uses Kaspersky Total Security for anti-virus.
I do not use Studio One as when I purchased my unit I already had a license of Cubase 10 Pro. I've been using it in a variety of settings for months with only minor issues (mostly user error) however, after the November update, it's basically unusable. If I can't sort this out, I'm saying goodbye to Presonus again (previous products have let me WAY down, and I stupidly tried again) but this time I won't be back.
