It is called a MIDI keyboard. It has a counterweight that is close to the feel of a piano. The counterweight is divided into full weight and half weight. The full weight is close to the feel of a piano, and the half weight is only half the strength of a piano. You can search for fully weighted MIDI keyboards on Taobao. I use the ICON LOGIC5 semi-weighted model, which is relatively cost-effective. However, I suggest you buy one with 61 or more keys, which can be used for making and practicing. I can’t play many songs with the 49-key model. I regret it
