After looking at this snippet:
http://lsr.di.unimi.it/LSR/Snippet?id=1058
I begin to suspect there's not a solution for the problem I just
highlighted: in fact in that snippet too the "new" pedal ( \sustainHalfOn )
has to be placed *before* a note, while the standard one (\sustainOn) has
to be placed after.
It would be *really* great if someone finds a solution for this, because
otherwise overriding pedals:
1) lead to inconsistencies in the code style (as the snippet above shows)
or
2) lead to verbose code (if we use something like \setHalfPedal
c'\sustainOn )
Also, please note that a fixed gap between pedals is very important in
music engraving...
Please give me feedback!
Best,
P
