I updated Mac OS to Catalina and Studio One to 4.6 - now, the audio starts to progressively deteriorate after about 10 minutes. If I change the device block size to any other setting the problem goes away for another 10 minutes or so, then creeps back. I'm running a 2019 MacBook Pro with 32GB of RAM, 2.9 GHz 6-Core Intel Core i9 into a Persons StudioLive 32. Default device block size is 512 samples which had no issues before updates. Any suggestions welcomed!
