In anticipation of my RD-88, I would like to try MAINSTAGE, which it seems to be made for smile. What is THE CHEAPEST MAC I can buy that will run MAINSTAGE? I've never owned a MAC and know absolutely nothing about them. Whatever you recommend, the SIMPLER (and cheaper and smaller) the better. Thanks.
