I just thought of something that I might have done - I turn OFF the aftertouch, because I seem to trigger it too easily with my left hand alot. I am not used to aftertouch, and I have a hard touch of my own, so the two do not always comliment each other. I may learn to utilize the effect if it becomes more important to me later, but for now - I leave it off. That takes OUT the vibrato that a lot of sounds don't need. I really haven't done much editing at all - just a few little "nudges" here & there.
