Hi Harm & hi Nathan,
Incredible. I'm shocked that this do-able.
Harm, the solution of overriding the after-line-breaking property on the
Instrument grob with a lambda especially blows my mind. Nathan, thank you
for expanding my understanding of context construction with a single
example.
Integrated into my score and it works perfectly.
Very much appreciated.
Trevor.
