I was pleasantly surprised by this midi controller. It is very compact and still has all the basic functionally you could expect. I am using it most of the time with my iPad, and the preset for Cubase got me everything working with zero config (faders, pan, transport controls, back/forward/repeat, selecting tracks, arming/muting them). The pads are good enough for a portable midi controller, and the note repeat can be configured and used easily enough.
It has arp/chord mode, and while I tested it and it works fine I don't really care for it so no much to say on this.
On a negative side, the daw controls are very "clicky" so if you want a silent operation this is not it. It doesn't bother me though. Also the keybed could be better, but for this size (and price) you are not really looking for premium feel anyway and it is on par or better than the competitors.
