It packs quite a bit of functionality in such a small device: It is surprising how small it is, but you get isomorphic key pads (what attracted me) that are velocity sensitive, three touch sliders, two axis motion detection, and audio engine, a 7-part looper, MIDI over USB and Bluetooth, and a very well thought out user interface that makes very good use of the small screen.
On the other side, it feels like more mature software would bring out the best in this thing: For one, the current release still doesn’t do MIDI (!), the buttons need more attention to software de-bouncing (though less of a problem if I were more confident and played harder!). The stock sounds are not particularly nuanced, but you can load 2GB of samples into it (and instruments can be built with samples mapped in pitch and velocity). The built-in effects are thin and could use more oomph. And the desktop app is clearly “first release”. All of this stuff is fixable in SW, so there is hope.
All that said, it is remarkably playable! Small enough to throw in your backpack, easy enough to plug in headphones, sit and just play. The keyboard system is brilliant, and even the looper UI is simple enough to just get out of your way while you play.
Once it has MIDI it’ll be in my live rig!
