Joram,
I stumbled upon a solution to this! It turns out that the second parameter
to extra-offset is vertical spacing, so for odd staff lines you can draw
the rest at the even line below it, and then bump it up by 0.5 with
extra-offset to get the desired effect.
This is what I came up with:
longbar = #(define-music-function (parser location pos) (number?)
(let ((offset (if (odd? pos) 0.5 0))
(staffpos (if (odd? pos) (- pos 1) pos))
)
#{
\override Rest #'font-size = #4
\override Rest #'staff-position = #staffpos
\override Rest #'extra-offset = #(cons 0 offset)
r2*1/4
\once \override Rest #'extra-offset = #(cons -1.3 offset)
r2*1/4
\revert Rest #'font-size
\revert Rest #'staff-position
#}))
Thanks again for your help,
Gabe
