I believe this is a bug, but if someone can explain why it isn’t and I just need to modify my set-up or workflow, then I’m open to ideas. On the face of it, this does appear to be a bug though (again, it might be down to me particular config!). Apologies for the long intro - but I want to set the stage correctly!
I have my audio interface (MOTU 828 mkii - old, I know, but it works) configured for Direct Monitoring. In general, this works beautifully - no latency, I can have effects inserts, the whole works.
I have disabled all of the MOTU internal mixes so I don’t hear the internal mixer (I just unmute them for live stuff when I’m not using Cubase)
My point here is - Direct Monitoring, in itself, doesn’t appear to be a problem. My audio routes aren’t complex either:
Physical Input -> Audio Track -> Group Track -> Main Mix (Output)
I have auto monitoring mode set to Tapemachine mode
My Control Room setup is also (I believe) pretty ordinary:
In VST Connections, I have a “dummy” Output tagged as the Main Mix
I have two Cue mixes (one to a headphone amp, and one to the mix-in on a VDrums module)
I don’t use the Phones output as I want to be able to Preview on either phones or monitors without changing preferences
I have Monitor outputs for desk monitors, headphones, and a couple of other outputs that are pretty irrelevant (hardly used).
When I select monitoring (the little speaker icon) on an Audio track, the monitor audio doesn’t come through until I ALSO select one of the Source Mixes in the Control Room. It doesn’t matter which Source Mix I choose (Mix, C1, C2) (even if it’s the one that’s already selected), but it does matter where I select it. So if I select a Source Mix from the Main CR section, I will hear the Direct Monitor audio. If I select a Source Mix in one of the Cue Mix CR sections, I will hear the Direct Monitor audio there instead.
I can appreciate that Direct Monitoring perhaps only be routed to one output or cue, but the issue is that if I then change the monitoring config on the audio track (the speaker icon) then this breaks the routing at the CR and I have to then re-select a Source Mix to re-establish the route.
Surely there should be some persistence to update the Direct Monitoring to the last selected CR Source Mix, or a setting in the CR to say which output should receive the Direct Monitor audio?
Or… after all that, am I doing something wrong?
