Just something I was wondering.

Whenever I do collaborations, eventually I'll check the file (the new one, that someone will have uploaded), and everything will be set to use MIDI instead of RSE, on every change, and on the automatic settings. I'm just wondering, is it just that people are switching it manually because the prefer MIDI (even though the distortion sounds like bagpipes....), or is this being done automatically for some reason?
Maybe they don't have RSE (or the files, which btw, I prefer bagpipe midi to) and are turning it off so they can hear the part play, then just saving it routinely like that.
