Thanks Rob! I ended up getting it fixed OK, but I’m attaching a picture just fyi. This is a harmonium part, as a mockup for an electroacoustic piece for contrabassoon and electronics. So the project has a bunch of staves. I know that the right hand staff is usually blue, and the lower staff red - I’m not sure how I changed this but it happened near the beginning of the piece (there was a cross-staff notation that probably started it - I don’t usually have voice colors turned on, I didn’t even realize this until just now).
Where it got frustrating - I was adjusting time signatures, moving these different voices around with alt-arrow, and it got to be a huge mess, stems going the wrong direction, lots of implicit rests, etc. It would just be nice to click on, say, the gold-colored voice and then know right away what it is. I still don’t know, actually - the contextual menu says I have 3 up-stem voices and 2 down-stem voices, but I don’t know which is which. Maybe I’m using it wrong.
(Incidentally, does anyone know what the contextual menu “Voices -> Default Stems Up/Down” does? I think it changes the direction of whatever color voice is currently selected. Is that right?)
