Rust has added MIDI instruments, and so people are going to be using MIDI a lot more over the next few months. You can only control 1 instrument at a time, so playing MIDI back into it: If it has more than a few instruments it can end up sounding terrible ingame. Removing notes or entire instruments is super easy.
Get your songs playing ingame to sound good.
