Assuming that it's okay and is applied, I've redone my docu patch. The
snippet prints a four-bar phrase with just the standard chord (to trap
the regression that bit us this time :-), then sets the capoPitch to
print transposed chords for the next four bars, then sets capoVertical
to print chords one above the other for the last four bars.
iirc that will then become the regression test for this feature?
Cheers,
Wol
