I got hold of a MIR 24 demo license, with the current promotion going on. I didn't opt for a room pack, since I wouldn't be able to afford that much at the moment.
Looking at the MIR tab in Ensemble Pro, I see a large concert hall stage represented, and I just assumed that I drag the instruments to where I want them to be, but I can move those harps no further left/right without straying from the hotspot. (They're part of an orchestra, and I want one mid-left, the other mid-right). Is that just because I don't have a room pack? Or have I missed something in the installation?
