Hey there.
I recently started using Cubase 10 and noticed that there was no pre-roll selected when recording and as soon as you select your value and turn it manually on, then it also stays on when just regularly pressing “play”. This is like driving me mad beyond diagnosis 
In Cubase 9.5 the pre-roll was only there when recording. Why would anybody need pre-roll when playing back? Please tell me I am missing a hidden menu or something…
Thanks!
Actually it had this behaviour before C10 too. Just tried it on a C9 installation and it definitely pre-rolls play too.
There’s a feature request to have the option “Pre Roll only when record” here:
