Only thing bothering me about it is the keyboard. It fits in the overall aesthetic, but I feel like they chose style over substance and regular keys would be more usable. Any comments from first hand experience?
It's a bit tough to play by itself, but I'm okay with the tradeoff for the portability.
FWIW it works quite well if you connect it to a MIDI host and use another controller to play or sequence the synths on it.
...just don't connect your 12v AC adapter to the OP-1's USB hub that wants 5v, or you'll lose all data connectivity (USB disk mode and MIDI) to the unit. :(
