Add bow sounds to Gong, Crotales, Cymbals, etc.

A Lot of the music I listen to, and compose, use the technique where one uses a cello or double bass bow and strum along certain instruments, creating a high pitch sound. It would be nice to have a feature like this. But then again, being that I am literally the only one who writes music including these features, I don't see why anyone would bother with a feature like this. screw me I guess.
