Check the listing for details. Arturia KeyStep Mk2 32-key Controller & Sequencer - White. Condition: Very Good - Refurbished. Listed at 125.10 USD. Commanding Sequential Power for Any Rig Fully integrating the appearance and control of the Mk2 line, the KeyStep Mk2 takes Arturia's coveted sequencing formula to impressively modern heights. It all begins with a familiar 32-note Slimkey keybed, complete with velocity sensitivity and aftertouch for maximum sonic expressivity. The KeyStep's notable sequencer and arpeggiator engines remain intact, albeit loaded with one-touch mutation tools, Chord and Scale play modes, and 16 arpeggiation modes that offer more versatile melodic foundations than ever before. Sweetwater producers were quick to note the addition of the Mk2 series’ onboard OLED display and push encoder configuration, making the KeyStep's profound polyphonic sequencing tools even easier to manage on any stage.
