One key factor contributing to a digital piano’s authentic feel is its keyboard action. The Smart Scaled Hammer Action Keyboard on the PX-S3100BK provides a realistic playing experience with its fully weighted keys, ebony and ivory textures, and authentic piano sound.

Items Worth Noting

  • I felt a subtle lightness in the black keys throughout my playing exercises across the entire keyboard. This discrepancy may affect the authenticity of the playing for certain players. We consider it a minor issue, but it is worth noting for those seeking a truly authentic piano feel.
  • Due to its compact design, the PX-3100 has a shorter key length than acoustic pianos, which may be challenging for some players, especially those who perform more complex classical pieces. This is something to consider if you’re a classical pianist. Yet, this is unlikely to be a significant issue for most players.
