The intuitive interface means that there’s no need for complex programming. Battery-powered operation allows complete mobility from desktop to street performances, or use in a variety of situations including live events in small spaces. 24 built-in drum/percussion styles that were recorded live using KORG’s proprietary “Real Groove Technology.” Each rhythm style includes a rich variety of patterns: two variations, basic, fill-in 1, fill-in 2, and ending.
