Since the last update the crashes have gotten worse and worse. Got the gray screen and had to CMD + control + power button forced reboot to get unfroze. Restarting in Safe Mode was how I finally got the machine back up and running tonight. Did a Hardware Test restart, then a Disk FirstAid and no problems found in either place.

FYI, PG Music, it acts like it's running out of memory, like maybe your code has a memory leak. Either that, or something to do with MIDI, because I'm running a Roland A-49 Keyboard MIDI Controller. Which, by the way, gives me no trouble in Studio One 4.

I'm one month on BIAB Pro. Before that, my machine was stable; never a crash.
