Is there a way to change the velocity curve or response in sounds like the nylon slide guitar or trumpet rx's? In order to get the "slide" effect in the nylon slide guitar, I have to hit the keys with a sledgehammer. I don't want to change my global key velocity setting, and don't even know if I'm looking in the right place. I just want the slide effect to sound sooner without affecting everything else. Can it be done to the sound without it being attached to a song or style?
