Chord Symbol playback
I have a score which started out with chord symbols on a single piano stave. All good. Symbols play.
I have since elaborated the score with other instruments still good. (score 1 attached)
Then on further development, score 2 they stopped playing though they will sound when mouse clicked on.
The chord symbols segment is a way in at Rehearsal Letter G
I am baffled. I tried a test Score 'chord Symbol test' and this was ok.
I checked for muting, play box ticked, sub channels faders up etc.
I'm guessing there's something silly I'm doing or not but I can't work it out.
