I see this is an old post, but since recently purchasing the Steinberg Ultimate Recording Package I too have run into this problem.
I have found a workaround, albeit a little messy in terms of the mixer layout but working.
I’m using the UR824. This has 4 stereo mix layers. My mission is to provide a rough mix to the performers with 6 “more me” direct monitor lines. (6 lines are fed to each aux in of a Behringer HA6000 providing the 6 headphone mixes)
When in Direct Monitoring mode, Cubase will only monitor live input to the single DAW channel on each of the UR824 mix layers.
(using the DSPmix24 app you can see the DAW channel next to the master)
Set the Line outs of the UR824 for each mix output (ie LINE OUT 1 & 2 = Mix1 L & R, LINE OUT 3 & 4 = Mix2 L & R…)
It is possible to add outputs to these in VST connections. (I see it’s called Audio Connections now)
So in there I have my main Stereo out routed to mix 1
Add 6 mono outputs and route them to the next Mix layers;
mono out 1 > Mix 2L
mono out 2 > Mix 2R.... and so on.
Now this is where it gets messy.
For each live channel you wish to record you’ll need another one for each foldback mix.
You can think of it as creating a separate mixing desk for each monitor output.
If the bassist wants more bass, create another bass channel, give it the bass input routing but set the output routing to whichever the bassist is on (in my case the bassist is plugged into channel 3 of the headphone amp, so route the channel to mono out 3 ……I’ll rename these later)
On this new Bass monitor channel, you can click the audio monitor button and it will send straight to that output assigned. Direct monitoring and latency free.
So I have the 16 tracks I wish to record. These are routed to Stereo out 1, armed and audio monitor is on. These are the channel I’ll create a rough mix with.
I have another bass track routed to mono out 3, not armed but audio monitor is on. The channel fader is used to control the send.
And one more vox channel for the vocalist on mono out 6 not armed, audio monitor on.
Looks messy, but I’m looking to find a way to group them in the visibility column.
Any thoughts and suggestions are welcome. I hope someone finds this useful.
