The app overall is no doubt one of the most complete music mixing apps available, in terms of variety of features. But the one reason I downloaded it was to use the sampler, and it is really just awful. It distorts any noise I try to use whether it be guitar, vocals or a random beat. I just dont understand what's so hard about simply letting me use the raw sound, and then edit it to my liking. Great app overall but not very useful for me.
