Work as it should with many functions you don't see on MIDI controllers. Especially with the built in synthesizer sounds. 10/10 Some don't like the plastic body but it's a superior textured plastic stronger than most plastic keyboards I have seen (and I've seen quite a few).
this is my second midi controller, tones are not that great, but you can tweak them. as a midi controller great device. gives a lot of control. keys are ok.
