From this mini-midi keyboard you have to say clearly what is expected of them: A piano keyboard, with which you can try out a series of tones and enter into the sequencer. But it works well, takes away much space and really has everything you need. The touch response is good, even though the keys themselves are very easy and simple plastic. About the controls on the left is leaving the field to a few octaves up and down, as well as keyboard shortcuts an arpeggio automatic adjust. A Sustain button to hold there also.
