I took a look at the troubleshooting guide, and saw that plugins could be an issue, so I made changes. The tracks used in this project are all exported stems from the original project. There are no plugins in use at all. And “Constrain Delay Compensation” is not engaged. Didn’t make a difference.
One thing I didn’t mention - on the performer end, the drummer says he hears a delay in his mic channel, even when we’re not rolling.
I mean “latest version” as of the post. I have dyscalculia, so I avoid typing long numbers because I’ll probably get them wrong, so it’s just easier to say, “latest version.”
