With a newly designed key mechanism ― taken from Roland's 30 years of synthesizer development ― players can control a wide dynamic range at will. The re-designed white & black key assemblies have a rounded shape for better reaction to the player’s touch and more comfortable glissando, plus changes have been made to reduce mechanical noise and eliminate vertical shake on the key strokes. In conjunction with this, the newly developed pitch bend and modulation design offers you easier and more expressive control. All these features add up to a keyboard that even the most discerning player can appreciate.
