The 88 note velocity sensitive keyboard is a semi-weighted action with medium tension. Carefully balanced with an even and dynamic response , the Impact LX88+ offers 4 velocity curves that gradually increase in dynamics so there is a match for any playing style. If you don't need velocity, 3 fixed velocity levels cater for a consistent output. The full-size, piano-style keys are covered to protect against dirt and dust while also complementing the Impact LX88+ design. Transpose buttons as well as pitch bend and modulation wheels are within reach, so you can quickly shift the keyboard up or down as needed, or apply additional articulation with the wheels.
