I can see some real potential with force touch and music apps especially on the bigger phones. One of the reasons I don't like playing piano on iPad is because it will try to guess the volume and it's off a lot. So random notes will just be louder sometimes. The smule app already has force touch to determine the volume of your playing based on how hard you touch the screen. I tried it and it worked pretty well. Does anybody else want to see this from GarageBand or other popular piano apps?
