The Casio PX830 BK Privia Digital Piano is focused on pure piano playing. That starts with the refined matt keys (ivory touch) with a pleasing playing action. The hammer and repeating action on the keys is just as luxurious as the 128-tone AiF sound source with Linear Morphing for dynamic sound behavior. The minimalist design provides a perfect counterpoint to the extraordinary wealth of sound. The “Black Polish” variant provides the PX-830 with an especially refined look.
