SIMPLY BAD, I did make the wrong choice thinking that a cheap Piano would still have a good sound, and the problem is it is not so cheap. paying 650 euros here is Germany is not so little. The Piano hammer action is just bad, and the tri-sensor is a scam. a Pianist might think it is three sensors for the hammer, no it is just a good old fashion cheap one sensor with the option to adjust the sensitivity from 3 levels. this is a scam. I feel I have lost those 650 euros, highly unrecommended.
Above all that, the Midi and USB function simply doesn't work, and the midi driver is no where to be found on the internet, and it is impossible to connect it to a new computer. simply a bad decision from my side. so do not repeat the mistake.
