Some pianos have national timbre, which is of course better, but it doesn't matter if they don't. For example, China flute can be changed into piccolo, dulcimer into harp, suona into trumpet, guzheng into folk guitar, erhu into cello and so on.
National timbre can include: erhu, suona, dulcimer, flute, guzheng, sheng, pipa, Ruan and so on. Here are eight kinds.
An ordinary piano has one or two sets of drum timbres. A better piano also has bad special effects.
The keyboard mentioned on the first floor refers to any electronic organ and piano with MIDI interface. Not a piano. Instead, any piano with an interface is connected to the computer, and then it is released by the special software of the computer, the sound card of the computer and the speaker of the computer. Even a shiny "keyboard" with no speakers and no buttons for adjusting functions can be like the one on the first floor as long as there is an interface. The keyboard itself took a few hundred dollars. But computer accessories are more than that.
In the electronic organ instrument, there is an electronic synthesizer, which can edit and process the timbre. A good synthesizer can sample any timbre directly from nature. The sound of rain and wind, the meowing of cats, is a trivial matter for them, but the price is high enough. No one can't take this piano for 10 thousand or 20 thousand It focuses on making music. If you are not a professional producer, you don't need such an instrument.
