So far, so good
I’m enjoying using this, having just bought it. It has tons of mapping presets, so you’re good to go right away, which is handy. I’ve got several other keyboard apps that can do drums - kB-1, for example - but this one is really well suited for drums, and the speed with which you can get cracking without setting things up makes it a really worthwhile purchase. I was initially wondering whether I was just buying another keyboard app for the sake of it but, rest assured, this one is very useful indeed. If only the developer would make his Keys app so that it can do chords with a single key, I’d grab that one, too (hint hint...!)
