AnalogAudio1 showcasing the classic Korg KR-55 Rhythm Box:
"The Korg Rhythm 55 (KR-55) is a non programmable analog rhythm box from 1979. The KR-55 and its little brother KR-33 were the successors of the Korg Minipops series. Same knobs as on the MS/PS-series. The sound of the hi hats is more complex - similar to those on the Roland TR-808/606.
The KR-55 has some special features: a TRIG OUT jack including several triggering modes, SHUFFLE function and volume faders for the most drum sounds.
The rhythms are not mixable like on earlier Korg rhythm boxes (Minipops series). TEMPO and VOLUME controls. It was used by Jean-Michel Jarre (Magnetic Fields) and Depeche Mode (Speak and Spell) among others. It has a very characteristic sound - it sounds fantastic!"
