Arranging keyboards or synthesizers are generally used in frequency bands, which are much higher than ordinary electronic keyboards. Compared with WIN98, these keyboards are just like WIN7 in timbre quality, richness and playing, editing and recording functions.

Moreover, when playing the piano, bullets are usually played according to the score, and even a wrong fingering will be criticized by the teacher. Keyboard players in the band don't need to be so rigorous, they just need a solid knowledge of music theory and harmony, and the ability to improvise, especially when playing live. As long as the chords are played correctly, they sound very harmonious, and the octave doesn't matter.
