8.    Duo Mode and Split/Layer Functions: The keyboard allows you to easily split the keyboard into multiple regions (e.g., bass on the left and piano on the right) or layer two voices for more complex performances. The Duo Mode enables two people to play the same range on the keyboard, making it ideal for music lessons or duets. These features are incredibly useful for solo performers or educators working with students.
