Ive got just about every good music creation app and this one in some ways beats them all. I would put it right up there with BeatMaker. Its fun and easy to come up with great-sounding loops. The samples are excellent. The sampler works great. I cant put it down. The way that all of the features in the app are organized makes it easy to be creative without stumbling over menus and buttons. Very intuitive. A couple of suggestions. Please make it possible to disable velocity. More often than not for me it gets in the way. I would also love to see, in addition to the gating, a quantizing feature for making beats. And wav expert would be awesome. The most important feature for me thats not there yet though is sample import. Quality is not great recording with the device itself. Even better would be integration with the Noise.io library. The way that BeatMaker implemented this is phenomenal, I use it constantly. But these arent shortcomings, they would just be features that are nice to have. One thing that can be a shortcoming is the limited space that you have to save your loops. I filled it up the second day. Its not too bad if you have basic recording equipment though. I just dump everything out into my lexicon adc and Start filling it up again.
