The KR55 (or KR55B) is a drum machine with ninety-six preset rhythm patterns instantly available for practice and performance. There's even a "swing beat" parameter to add subtle variations to particular songs.

The volume of each sound is individually adjustable so you can bring up the snare, for example, or cut out the hi-hat to suit your taste. These highly realistic patterns can be used independently or synchronized with synthesizers and sequencers.

Start/stop & intro/fill-in functions can be triggered by foot switch.
