It sure would be nice to not have to kill and restart the Cubase process after exporting audio.
It very often is the case that if I render a new audio file without the “Realtime” option on, the Cubase interface becomes non responsive. If I export and overwrite an existing file (where Cubase has to put up an “overwrite?” dialog), then I have never seen the behavior. But making a new file most often causes the interface to die.
