Why not allow users to simple type Note Names or Info directly onto the notes in the PRV? For instance, let's say my samples have some keyswitches I want to document in the PRV. Right now, the closest thing is to create a drum map, which isn't always helpful or efficient.
I'd like to just double click on a key in the PRV and enter the note names or whatever other text I may want and have that text appear on that particular track's PRV only.
