if you are getting hangs when exiting, that is usually due to a plugin. try navigating to your VSTPlugins folder and rename it to VSTPlugins_OFF or something. that way when cubase loads it wont load your plugins.
Then try loading in the project and closing it off. if its noticeably quicker upon exit, then slowlt introduce the plugins one by one until you find the one causing the slow down.
then, once you have found it, look for either an updated version, or if you are on 64-bit cubase, consider installing 32-bit cubase alongside it.
this does not have to do with hanging plugs. as i said i just open C6 empty and close empty. no loading of plugs involved.
but i take your answer as an indication that you do NOT experience such long shutting down times?
and to my 2. point: how long does closing your preferences dialog take?
can anyone give a hint at how to troubleshoot something like that? it must have to do with my installation then, but how to pinpoint what causes it?
i went back to my initial install with C5 on it. opening and closing times are just a few seconds there too.
This may be related to the audio driver resp. ASIO driver. Cubase tries to unload the driver on exit and may have to wait due to numerous reasons. Try to select no driver in the Cubase devices setup and try again.
problem solved.
it turned out to be in the general preference file.
i deleted all preference files. after that closing was fast (3-5sec) and same for the preference and device dialog.
then i restored one preference file after the other. after i restoreed the general file the slow fault showed up again.
i then even narrowed it down to a specific cofiguration preset in the preference dialog. i did not go further to find out which setting within the preference dialog was causing the upset.
