(This is a guest post from James Martin of midemblog. Evolver.fm is an official publication of Midem 2012 in Cannes, France, where Evolver.fm editor Eliot Van Buskirk will appear on panels and judge the following midemlab music apps. We figured we’d repost midemblog’s lists of the finalists in midemlab 2012, which includes videos and descriptions for each app, in the spirit of not reinventing the wheel.)
