It is not what I expect

I am very much desapointed with this App. It´s probably good for begginers, but not for professionals. So little good rhytms, few options, and the Rhythm&Timing is ridiculous. Just buy this if you are a begginer. Also it does not work when you “drag” the wave to Pro Tools. Pro Tools do not reconize this file. I am frustrated… I lost 15U$.
