I run Finale 2014.5 on a windows 7 version.
I'd like to hear only on the 2nd time some instruments in my score.
I created an expression (hidden) called tacet 1x with controller 11 at 0, and a second one called "2nd time only" with controller 11 at 127.
It works at the beginning but as soon as the line encounters a smartshape (that would nromally play 2nd time), then I hear the notes the 1st time.
I don't know if I'm clear enough (french).
I enclose the exemple (screen capture).
The trombone, tenor sax and baritone should be heard only 2nd time, but on measure 5, I hear them ...
Thanks for your help.
