Comping options

It would be nice to have the option to indicate the player that a particular chord needs to be played on the downbeat instead of playing it after or before the beat.
It could be a marker placed over a chord (just like the END marker), but this one would force the player to play all instruments on the downbeat of that chord.
It's possible to emulate kicks in a song by using different time meters, but in order for this to work properly, the rhythm section needs to play those chords the downbeat
