Hello,
I'm a Windows/Reaper user. I had Mixbox 1.5.0 working fine, but I updated to 1.5.1. The result was quite chaotic: Mixbox projects wouldn't load. I went back to 1.5.0 and everything worked fine again.
Last week, I updated to 1.5.2. It wasn't as chaotic, but it was quite problematic and difficult to understand: there was a huge change in Mixbox's CPU usage. I had 10 or 12 instances of Mixbox in my projects, and it worked fine with 1.5.0, but not with 1.5.2.
I switched back to 1.5.0.
I'm surprised no one else is complaining about it. Is there anything I could test or provide you some information to investigate?
Best regards.
