Hi,
found some code on the list (can't say anymore who posted it
initially) and extended it a bit. See attached.
It completely avoids \cadenzaOn/Off, because of the hassle you experienced.
midi may come out strange (not tested), I don't care about midi, though ...
It's 2.15.24 code, but still working. Anyway running convert-ly over
it may be a good idea.
Maybe it helps,
Harm
