Unfortunately the same disregard for intuitive design that plagues most hardware-based sampler/sequencers is at full tilt here. Not only is the app completely disorganized, it also ignores almost every single interface standard that iOS users are accustomed to. Top that off with minuscule buttons and controls that are impossible to use with normal adult fingers and you've got yourself a frustrating waste of $4.99. I thought Apple reviewed these things before they put them in the store...

Many issues that are to be corrected. The metronome is irregular, the sequence window unstable. Recording an instrument, the note does not fit with the keyboard and no way to adjust it. When importing a sound from iTunes, it records the whole track and there is no way to cut out the sample I need. There are much more issues but first of all it is the instability and not practical interface at all. Cannot use this sampler, and for this price, will ask my money back
