I agree entirely. I use it a lot, even though I also have Finale Allegro, since so many tunes on the web are already in ABC. Otherwise I would have to type everything into Finale.
Yep. I use it especially when I want “pretty” music staves, like for the tune book I do for my annual SummerTunes workshop. You have a bit more control over the appearance.
I don’t do anything in grand staff or orchestral arrangements, or even (usually) voices, but it’s more than capable of handling them.
