I have been experiencing numerous problems with Cubase 9.5 Direct offline processing. This is still happening in 9.5.30.
When auditioning a change, Cubase 9.5 is turning off / bypassing plug-ins on the Stereo Out channel, including post-fader inserts.
But when you finish auditioning, it’s not returning those plug-ins to their correct previous state.
I have uploaded a video to demonstrate this here: https://www.youtube.com/watch?v=jxjcpljutuc
This means that some plug-ins are not turned back ON, and some are turned ON when they were bypassed before the direct offline processing.
With some plug-ins, it may be obvious when this has happened, but others not, and as a result, you can have plug-ins on that you expect and think are off, and vice versa. I have noticed on a couple of projects where this had happened, before I realized what was going on, that the mixer history becomes corrupted and screwy after this. It has made a complete mess of one of the projects.
Aside from fixing the problem, I think also there should also be a setting for the post-fader slots on the stereo bus, as there could be good reason to have them on whilst auditioning, e.g. a brickwall limiter etc.
I don’t why they just did not feed that audio to the st out at the post-insert point, pre-fader, thus bypassing the inserts altogehter on the st out channel and not needing to turn the inserts on/off.
But this needs fixing in my view. If you’re going to switch plug-ins into bypass, you need to return them to the state they were in. And currently, what they’ve implemented is not doing that properly. It’s so frustrating and time-consuming with these issues.
