I’m trying to use the Walker 7-shape to match this (The Christian Harmony, 1867, William Walker), which is an authoritative source for his 7-shape system as far as I know:
But the shapes aren’t quite right. Do is upside-down.
Also, the half-moon Re is reversed; it should open to the right.
Lastly, the stem on Do attaches at the center of the notehead, not the edge. No idea why. I can’t change the attachment points in the notehead set editor, because it messes up dyads.
