Really Presonus it's about time you sorted this issue.
Since version 3 for goodness sake.
Studio One hangs for several minutes. Not sure if it's BFD3 that started the issue but after bouncing down ALL midi tracks to audio (not using convert to audio as that created even more issues with double layers...) I still have these hangs.
Makes working with midi (never your strong point S1) a really disaster. Also packaging .fxb shows up too.
Latest version on Sphere but at this rate I'll be looking at Logic X again for all my midi work.
I'll file a ticket but this has been a problem for a very long time and it's extraordinary that it hasn't been resolved.
Oh, and I now see how difficult it is to raise a support ticket, log into Sphere and all I get when I click Support is my profile and a list of videos I surely would enjoy. And clicking on the main Support header on the website takes me to a page that asks me to log into my Sphere account and click support, (even though I'm already logged in) - annoying and frustrating.
