The new KR-11 is a compact yet feature-packed rhythm machine, which offers a portable solution to bring variety and fun to your music practice. The KR-11 compact rhythm box brings the rhythm machine legacy into the modern era, pioneered by the legendary Korg Doncamatic in 1963.
Simply choose your favorite genre to get started! Each genre includes 14 variations for a total of 126 distinct patterns, as well as 14 dedicated slots where users can easily save their own unique patterns, taking your practice sessions to new levels of enjoyment.
KR-11 is battery-powered, lightweight, and compact. The built-in speaker allows for easy on-the-spot playing of a wide variety of rhythmic phrases. In addition to fundamental patterns like 8-beat and 16-beat, the KR-11 features specific styles like ‘’'Blues/R&B,' and ‘'Country' tailored for guitarists and ‘Island' for ukulele. Beside three-beat patterns the KR-11 also features more intricate five- and seven-beat patterns. The swing function adds versatility to each pattern, expanding the range of variations.
The KR-11 also includes a metronome function for fundamental practice, making it an essential tool for a broad spectrum of musicians, including guitarists, bassists, keyboardists, and orchestral players.
The KR-55 Pro provides a rich array of input jacks that accommodate a variety of instruments: a guitar or bass can be connected to INPUT 1/2, and the XLR jack accepts a mic input. You can let the KR-55 Pro take care of the rhythm, and enjoy a full-band performance with guitar, bass, and vocals. A reverb effect can be applied to each input source, and TREBLE and BASS equalizer are also provided so that you can shape your sound in detail. The AUX INPUT supports stereo, and can be connected to a digital audio player, a keyboard, or an effect unit that’s equipped with stereo output. Together, they allow you to use up to four channels.
An optional pedal switch facilitates start/stop, pattern change, and fill-in operations in pattern play mode, allowing you to effortlessly control the KR-11 without using your hands.
In Pad Play mode, the pedal switch allows you to play any drum tone for a more authentic drum-like performance (bass drum and hi-hat are pre-assigned at the factory).
The KR-11 also includes a headphone/line-out jack, providing the option to connect it to a PA, mixer, amp, or other devices, allowing you to play drum phrases through monitor speakers. It is so easy to do small guitar performances when running your KR-11 with a guitar amplifier.
The 16 pads on the unit are assigned drum sounds such as the bass drum, snare, hi-hat, and cymbals. These pads can be used for a great finger drumming experience! The built-in velocity function responds to the strength of pad strikes, enabling the creation of more realistic drum patterns.
You can also save your pad performances to the user bank, enabling you to play back your favorite patterns at any time.
Compact, battery-powered, and equipped with built-in speakers, the KR-11 makes it effortless to enjoy performances on the street, outdoors, or anywhere else.
The newly developed speaker system is compact yet powerful, delivering a wide sound range and natural resonance. Additionally, the Acoustage Bass technology helps reproduce the deep bass sound of bass drums.
