One question I must ask:
"Did they release Studio One 5 too early, or was it too late? I this strange time of Covid-19, perhaps the original plans for a release date was changed? Finally they just had to get it out, knowing the bugs will float the surface in one way or another.
As for now I really can´t work with the program at all. I don´t use any aux channels since I use an Apollo sound card with very low latency and plenty of plug-ins for my external devices. My external gear like Moog One, Rev 2, Voyager will cause the program to hang totally. The only way to solve the problem is to force a quit. Now, the things I do with my external synths is not in the field of rocket science. I simply play some notes, tweak some knobs and voila...it crash.
However, could it be the computer itself? Well, before Studio One 5 I had everything running smoothly with out any crash. Not even a single time. Studio One 4 was stable. It´s a new Mac, freshly installed so there is no reason to suspect anything in that direction.
I would appreciate any feedback from Presonus about this problem.
