Question

Spontaneous latency started after the 4.6 update.

I have been using DAWs for over 20 years and encountered most of the common issues.

This latency and lag is a different beast though, and even though there are an ever increasing number of us presonus keep denying it exists and wont provide real time support for fear of accountability and financial repercussions.

Answer 1

That sucks dude. But if it started with 4.6, downgrade to 4.5.5. Log in to mypresonus > Products > Studio One 4 - more details >  View Previous Versions. And then I'd disable check for updates.
