Some actions lend themselves to global action. In most cases a key change is a global change whether you're working on a piano chart with only two staves or a concert arrangment with 16 or 20 staves. The ability to select a global change will save a lot of time. Tme signatures usually have the same global impact. The ability to make a change from 3/4 to 4/4, for example, will save a lot of time and key strokes. Thanks for any consideration.
You need to add a better way of doing drum rolls!
