I would like to replace my yamaha mo6 with a midi controller and mainstage...if I need say 10-12 different instruments for a show, how feasible is this as far as loading time for instruments that aren't native logic? Also if I purchase any of these fantom/triton/motif dvd's, can I load those sounds I want into exs24 and will I have lag or crazy loading time for live use? Also if I had something like vir2 vi.one how well would that work? thanks in advance MBP unibody 2.66, 4gb ram, 10.5.8 Mainstage 2.1
