Tried splitting a complex arrangement (Chicago by Sufjan Stevens). Drums bass and vocals come out fairly well, though the drums stem seems to lack other percussion elements outside of the core rock drumkit (e.g. tamborine), and cymbals hits are clipped rather than ringing. The 'other' stem, the rest of the instrumentation, keeps a fair bit of the percussion and there's bleed from the vocal melody. The backing vocals seem to have disappeared for the most part, and are only audible in the vocals stem when the lead vocal is present (like they're reverse-ducked? Been a while since I did any production, the terms have escaped me...). Not much use with complex arrangements to be honest, I was hoping to get things like the strings section separated from the rest of the arrangement.
