I notice that if I specify Rehearsal Letters to appear over the top staff and over the keyboard part
- If I put a piano reduction below the vocal parts, the Letter shows there but not above the band’s piano part near the bottom of the score.
- If I create a Conductor score that eliminates the rehearsal piano part, then the Letter shows up above the band piano part as expected
So apparently, with multiple keyboards, the rehearsal letter will appear (if requested) only above the first instance of a keyboard part from the top of the score.
Not a complaint, just an observation. I can see how this would make sense in that one would not want a rehearsal letter above every woodwind part if one asked for it above the woodwind section.
