My first impressions: nice sounds but very awkward UI. But the deal breaker is the controls themselves, some of the very worst Ive ever used on iOS! The knobs ...sorry, the potentiometers are completely wonky and near impossible to adjust finely. Also, when you try to adjust one thats in a column of several, the entire column turns blue, then you cant adjust another knob in the same column without touching outside the highlighted column to deselect it first. Seems like a small thing, but it really kills the workflow. For $4 this app is just not ready for prime time, Ill be waiting and hoping for an update and would advise against purchasing until one happens.
