KORG KR-11 Compact Rhythm Box

The KORG KR-11 is a compact, battery-powered rhythm machine that brings 60 years of Korg drum-machine heritage into a modern, portable package. It features 16 velocity-sensitive pads and 126 factory patterns across nine genres, with space for 14 user-created patterns—ideal for musicians on the go. Whether powered by four AA batteries or an optional 9 V AC adapter, its built-in speaker with Acoustage Bass technology delivers rich sound anywhere. A metronome and swing function expand its practice-tool versatility for guitarists, keyboardists, bassists, and more.

Intuitive controls let you select a genre, choose a pattern variation, and hit play in seconds. Customize any pattern and save up to 14 favorites for quick recall. In Pad Play mode, the KR-11’s pads become live drum triggers—assignable via an optional PS-1/PS-3 pedal—for authentic finger-drumming performances. Expand functionality further with footswitch-driven start/stop, pattern changes, and fill-ins without lifting a hand.
