The Korg Taktile is absolutely loaded with features, such as a touch pad inherited from the Kaossilator that lets you play melodies using just a single finger, velocity sensitive drum pads, as well as rhythm patterns and arpeggiators. It provides all of the basic controllers such as sliders and switches, and makes setup easy so you can start producing music right away.
