I am not so convinced Cubase 9.5 is so great. I have only tried it out for several weeks with minimal sized projects and already I have had to trash the preferences file twice to get the MediaBay from freezing up after a simple selection. Seems that adding content files to 'my Favorites' in the MediaBay gets Cubase in a tizzy. A complete reboot is necessary after each of these 'Cubase' freezes, and Windows10 Task Manager doesn't help as the program cannot be 'ended.' And after 10 days there is no response from the Steinberg help desk other than the obligatory 'we got your request' response. A Steinberg forum member did clue me in on allowing Cubase rebuild the preference file, but there seems to be something else going on as it has now happened twice in a very short time.
I can say that Sonar crashed on me a hand full of times in over 5 years, and usually it was associated with using Melodyne with too large a clip. Samplitude PROX3 has also been very stable on my system.
the biggest thing I will miss once the Cakewalk servers go down is this forum. Members have been very helpful.
