The file I posted is only intended as a tiny file to show my current problem.
I could post something longer but I dont think this would give the experts
any better idea of my problem.
In outline, I wanted to
print out a \score with the handbell music in plain black, collecting
information as it goes.
call a Scheme procedure to assign bells to ringers. In my example
"shout" stands for this procedure. My problem is: how to get "shout" to
run after the first \score is printed?
Then do the Scheme equivalent of
for ( i=0; i<n; i++ )
print the \score again, highlighted for the i-th ringer
