I just hacked together a couple simple functions to streamline the process of
divisi writing. They basically work, but I have a couple issues. First, why
does the instrumentCueName display three times? Is there a way to get it to
only display once? Second, it's a bit annoying to have to enter \voiceOne
and \oneVoice in the non-divisi voice. Is there a way to e.g. set \oneVoice
not for the current context, but rather for a different named context?
