We should pay some attention to this when choosing a piano digital. Although there are a hundred or even more than two or three hundred tones that an electric piano can be enriched, don't blindly pursue the number of tones. The most important thing is the sound quality of the electric pianos.
Don't forget, you are buying digital pianos, not an electronic piano. The real piano sound is sampled from the grand piano, which is combined with modern ultra-real sound sampling technology. While the electronic keyboard sound sources are inferior, they are actually a variety of synthesized sounds.
