It definitely helps! Thank you.
For my better understanding, could you explain exactly what is
happening here?
I take it that \arpeggioArrowUp applies to a Voice context, and that
somehow setting PianoStaff.connectArpeggios to #t doesn't alter this
fact.
But I don't understand what the 2 \reverts are doing in the new
definition. What are they reverting to? Perhaps #f and 0
respectively?
In the light of your reply I have now altered my file, and after a bit
of experimentation I find that all I need is:
\set PianoStaff.connectArpeggios = ##t
\override PianoStaff.Arpeggio.arpeggio-direction = #UP
and then
\revert PianoStaff.Arpeggio.arpeggio-direction
when I no longer require the arrow (which is after the first
arpeggiando in this case).
