I bought this keyboard because it is lightweight and portable and I am gigging a lot these days. The sound, knobs, keys, action, polyphony is all fine (the best you will find at this price) but the deal breaker for me is the touch sensitivity. I have played hundreds of keyboards in my life and only very few of them (some cheap clavinovas) had problems with touch sensitivity. The main problem is that this keyboard registers what I would consider a medium, mf touch as hard, ff. It is nothing like a real piano let alone a typical digital piano or keyboard. I have tried adjusting the 3 touch sensitivity settings, using the keyboard as a midi controller with a third party app (pianoteq) in which I could customize the velocity curve, a combination of the two, even adding compression to the audio output, and nothing worked. It is still registering everything as fortissimo, velocity = 127... and there is no way to play dynamically this way. It is a shame because if it were not for this problem I would easily give this keyboard 5 stars.
Also the sustain pedal is difficult to use but it does work just fine.
