specific-note-only select and transposition

[--THEWILLBR--]

say you want to select all of a certain instrument in a specific area but there are other notes in the area. if you don't add this "filtered selection", our only choice is to select them ONE AT A TIME. That's a waste of time.

I also want the ability to, with a single click, shift every non-percussion note up or down by a set amount of notes.
