The only bug I ever had seems to be fixed. No more random crashes during exit and save and heavy midi editing.
At least I've gone past the point were in the past I would have had at least one crash. Who knows why those crashes happened but my solution was to save and save and save as I worked. I have now stopped doing that. I still save a lot but with splat I would do it every 3- 5 minutes or a crash would be pending.
