If you want to employ a different output configuration than the default (probably still mostly stereo) for your project, you will first of all have to define the desired output format in your DAW.
To get the right number of output channels in MIR Pro 3D, you can, e.g., create an audio channel in the desired format, and then define a MIR Pro 3D insert for the channel. The number of Capsule Outputs in the Output Editor of MIR Pro 3D will be set accordingly.
Caution
It is not possible to change the channel configuration after you've defined the settings of the first MIR Pro 3D insert! Trying to do so may destabilize your system. To prevent this, always start with the maximum speaker configuration. You can add stereo channels to a surround environment, but not the other way around.
Warning
As a panner in Cubase / Nuendo, the channel configurations of MIR Pro 3D and the host’s active “Main Mix” must be identical!
In VE Pro, click the New Project icon on the Menu Icon Bar at the top, or select the respective command from the “File” pull-down menu. A dialog window will open and ask you to select the desired channel configuration; please select a format from the list of pre-configured setups.
Important
MIR Pro’s Output Format is not the to be confused with the overall channel setup! It is very well possible to have a MIR Pro stereo setup running in a VE Pro 5.1-surround frame. Likewise, choosing a surround setup for MIR Pro’s Main Microphone will not change VE Pro’s global channel settings.
The new Vienna Ensemble project will create a Master Bus with the chosen number of output channels, including a full-fledged panner.
Tip
While it is not strictly necessary to do so, it might be a good idea to delete any panning devices from VE Pro’s Mixer that aren’t needed, just for the sake of clarity. In fact, when working exclusively with MIR, no panners are needed at all as its engine takes care of all positioning issues.
