Just chiming in after the new update (4.6.2) - still crashing. Playing the track, mixing, TRACKING, editing audio, opening a VST, few VSTs, lots of VSTs, browsing. I get it all after 4.6, at least once a day. Audio engine freezing, loud repeating millisecond worth of audio, until StudioOne decides to finally close the process after manually closing it (sometimes takes a few minutes, during which I have to shut my monitors off and just twiddle my thumbs).
I'm sadly looking at ProTools now, as this is just unacceptable - ESPECIALLY when I'm working with a client behind me. It's nuts. Never been more embarrassed by something I've spent hundreds of dollars on.
