The UNO is just lightweight and easy to use with good sounds. It���s not the best synth I have by a long way but as part of my gigging set up its perfect. The ���keyboard��� takes some getting used to if you have never used one of these, but is better than the Volca ones as it is slightly more tactile. The only improvements I would like to see would be an internal speaker, like the Volcas and Novation Circuits have and more connectivity options. But for the money, it���s pretty good and a welcome addition to my kit list.
