Studio One 6 add to glisando to option glisando playback it follows scale.(harp needs such glisandos for example). Also option black/white notes glisandos as well sometimes chromatic percussion glisandos are played such way even scale is something else. and i bet these are not only one uses and i feel best place for such setting is when i select glisando right mouse button there is nice idea place where such details should be adjusted.
