I compose snare drumming scores for bagpipe band style rudimental drumming. The only thing that I can't figure out how to do that I've done before in other software (I mostly use Lime), is to draw a bracket over sections of the music that in my genre is used to denote unison playing. That is, in a score with repeats, the first time through a lead drummer plays everything, while the corps members pop in and out for effect. That's denoted in the score using a bracket above the sections where everyone would be playing on the first time through.
This is an example via Lime: http://pbdrumming.scottarmit.com/scores ... t-2004.pdf
Anyone know a way to do that in ABC or one of the interpreters?
