I am having this same exact issue with my iMac and the quad cortex. Probably need a firmware update to address USB issues.

I just had this occur and posted. Sorry about that…I didn’t see this message before. Has this been resolved?

This happens to me regularly.

QC over USB into Logic X 2020 MBP. Software monitoring.

Sometimes it takes awhile to occur, other times it happens every few minutes. Extremely annoying. I’m beginning to think it’s an issue with Logic or Catalina. I usually open logic preferences and disable then re-enable the audio engine. Unplugging and plugging the USB fixes it too but only temporarily.

If I monitor the audio straight through my Audient id44 (XLR) I never have any hiccups.

So, something is wonky with the USB, or Logic and Catalina. I can’t narrow it down beyond that. My helix over USB never had problems. I sure hope this gets resolved.

Did anyone discover a solution to this issue?

I have just got a new QC and am having the same long-latency with audio over USB into a Catalina 2018 MacBook Pro with Logic X. I get the same issue when monitoring the audio through another program, so I don’t think it’s an issue with Logic.

A friend owns a 2017/18 MBP with Catalina and has all kinds of latency issues with just about everything via USB including his QC. He thinks his issues are due to Catalina and still investigating.
