I'm trying to use this app on my iPad and I find it rather frustrating. It makes me enter one note at a time and can't sense what I'm playing or what tempo it is at. Then if I try to edit it, it takes too long. It's not very intuitive. I have a feeling if I were using a midi it would be smarter but I wanted something I could use without a midi on my iPad alone. So far, it's too frustrating and the technical problems inhibit the creative process.
