Read Matthews review below on which I agree too! That and some basic guide lines or tutorials would be nice like the qualities of boosting and cutting certain frequencies so that u can have a point of reference if Ur a beginner instead of a hit or miss approach. That and adding a range limiter so u can practice a certain octave would make this app a juggernaut. But Im still happy as hell with my puchase.
