The ultimate drum sound, anytime and anywhere!

Numerous rhythm patterns built into a practical interface! The new KR-55 Pro is a multi-function rhythm machine that’s also equipped with mixer/recorder functionality.

Experience the same musical support as if a pro drummer were sitting in on your session. The KR-55 Pro gives you an easy way to enjoy jam sessions with the backing of real drum/percussion sounds. It provides a rich variety of input jacks, mixer functionality, effects, and equalizer, as well as a versatile recorder that can record to an SD card. 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.

The KR-55 Pro features “Real Groove Technology” which uses data recorded from actual professional musicians performing at various tempi, and is a completely different technology than conventional rhythm machines. There are a total of 24 high-quality rhythm styles, each fine tuned to provide the best possible feel, to accurately reproduce the experience of playing with a percussionist. The sounds, grooves, and phrases will play back at pristine quality even if you change the tempo, so you can enjoy playing serious jam sessions at your own pace.
