I should add that the "algo-reverb strapped across the master bus"-approach works for broad, floating themes with the occasional accent now an then, or airy compositions with lots of space between the notes and lines - not so much for densly packed arrangements of music based on a steady beat and/or lots of fast movement, with little inner dynamics. In the latter case, you're better off with pre-MIR Aux-sends for specific channels, most likely.
