There is no "just do this", there's only deciding which rules of thumb to apply to each bar. I basically have to go through the whole score, one or two bars at a time, and do various little tricks to try to get it looking like a score for a single monophonic instrument, or close enough.

I've seen bars that were entirely in voice 2, for example. In my case, I'm never the one that allocates the notes to the particular voices - it was done by the MIDI import routine, and the pattern to it, is not immediately obvious. This answer is preferable, because I don't want all rests invisible, and I wasn't aware of it, so I'll add that step. I feel strongly that no one should ever have to do that again. Ultimately, I go through it hiding individual extra rests which are just cluttering up the page, and then hide all invisible elements. I try tricks to remove them, like swapping voices 1 and 2, in bars where it happens the most, then deleting all rests - which usually generates a few more. Rests are what happens when no fingers at all are busy playing a note. Put simply where there's a note playing, there is not a rest in the same place. Please make that stop, in the new version. I can't imagine anyone sitting down with a quill, writing out some music with the odd chord in it, and deliberately writing in rests over the top of notes - unless they'd lost their marbles, possibly. This happens a lot when I import from MIDI, and there is more than one voice on a stave - e.g. It's not that I'm fussy, or a neat freak - they make it harder for me to see the notes I'm trying to play.

One thing that really bugs me is having to clear up the clutter of extra rests, which shouldn't be there because one of the voices in that bar is playing a note.
