I’ve noticed that Cubase 6.5.2.141 will crash if I save immediately after hitting stop. It seems that some plug-ins have problems if the audio is still processing or something, and the whole program crashes (“EXC_BAD_INSTRUCTION (SIGILL)”. If I press stop, wait two seconds, then hit save, everything is fine. But sometimes I get too involved in the session and hit save too soon, boom it crashes.
One of the plug-ins that does this is Kombinant DVA from Audio Damage. I have contacted them and they said that there is something happening on the Cubase side they can’t control. The Buss Compressor from SSL also appears to have this problem.
It may be that when you hit stop, the plugins are still processing and returning audio (due to their latency).
This means that Cubase is still processing the audio for a few milliseconds even after you hit stop.
(Please note that this is an untested hypothesis)
I just bought the GRM Tools bundle and Cubase crashes every time I change plug-ins.
If I bypass the plug-in and then change, then it works. If I just change plug-ins, there’s a decent chance that Cubase 6.5.3 will crash. I have this problem with Audio Damage plug-ins also.
