That depends on what grade of piano.

　　There are at least 10 timbres for 300 and 500 toy pianos in supermarkets. And there is a big gap.

　　Ordinary regular electronic organ, more than 2000 can have more than 100 timbres. Conventional musical instruments and musical instrument combinations have almost all timbres. Too similar, such as the viola, may not be available because of the violin.

　　The mid-range piano can edit the timbre. It can make dozens or hundreds of continuous transition timbres between piano and electric piano timbres.

　　High-end tens of thousands can edit music more freely, and even physical waveforms are new. In other words, hundreds of transitions can be made between piano and trumpet.

　　With more than 20,000 or 30,000 pieces of piano, you can create your own music and collect timbre from nature almost without restriction.
