I have read this answer, which relates to a different problem.
I want to know how to include a note to be played at the start of my first bar (ie: within the bar, not prior to it), but only during the first repeat, not the initial play-through.
The first play-through commences with an eighth rest. On the first repeat I want to put an octave chord in place of that rest. Is there some kind of bracket notation that is used in such a circumstance?
Any advice which includes how to do this in Noteflight would be even more greatly appreciated.
