Hi everyone, this is my first time posting here, so I hope I'm going about it the correct way.
Does Gregorio offer support for multiple staves as in the attached PDF? I'm working on some new music for Christmas and I need to have 2 staves of gregorian notation happening at the same time. Currently LilyPond is the only software I know of that can accommodate what I need, and it does a pretty unsatisfactory job at that. I was able to do the Introit but it took so much effort and I'd really like to be able to use Gregorio if possible.
