In the Alan Meyerson video, near the end, he mentioned that in one project he was using the MIR Pernegg Monastery as one of his two reverb sends, alongside his Bricasti's in the other send. I know it is pretty common to have two different reverb sends like what he is doing, but to me it seems a bit unusual to have MIR in this spot as then you are really not using it as a positioner, it is instead just being used as a regular convolution reverb for the particular impulses.
I'm wondering how this is accomplished, given that I cannot see any way of turning the MIR positioner off, in the same way that the Altiverb positioner can be enabled and disabled. Is there some way of doing this, or is there some position and width setting that will behave in a stereo mix as though a positioner was not being used? I would think that the positioning settings in MIR would mess up signals that were already positioned in the room, making it difficult to use it as a send effect like you would with a regular reverb.
