Recording out of sync by exactly one 16th note

When I say “via the monitor” I mean from the feed that’s controlled by the VST Connect editor directly to the right of the Talkback control. After following your advice in the posts above, I ensure that Track Monitor is not engaged on the performer track.

When I say “crashed” I mean a full crash - completely gone with a crash log displayed. Cubase hung several times as well. Where can I find the crash log to share it?

Details on my machine:

I’m on a VDSL connection with 40 Mbs download and 17 Mbs upload. The other end is on a fibre connection with 150 Mbs symmetrical.

On the other end, all I know is a laptop running Windows 10 and VST Connect Performer 4.042 with a Samson C01U USB condenser mic.

And I’ve read the post you referenced, and have already followed all the recommendations.
