Fading and Pitch

I really love this app and it has helped me with all of my songs which can be hear via soundcloud @$hmoney$ix. But I have been longing to do dubstep and a softer song but there is no pitch control for if I want a certain note to go higher or lower in pitch; and for slower songs I wish there was a fade control and not like how the volume gets quieter but if there weere a fade control to make like a final note of an apple loop or custom note to slowly fade and be longer instead of just ending. So I relly hope that there will be a new update soon and hopefully this is added.
