Glitch

Ive been using this app for a long time and its great but lately when I try to play patterns they dont repeat and the sounds glitch. I had to delete the app and download it again to get it to work before and it worked fine for a few days but then started doing the same thing again. I dont know if it makes a difference but Im using the app on an iPhone6s plus.
