Boss DR-01S Rhythm Partner Drum Machine

ORGANIC GROOVES FOR UNPLUGGED MUSICIANS

Introducing the DR-01S Rhythm Partner, the world’s first virtual percussionist designed specifically for acoustic musicians. Unlike the rhythm machines used by electronic musicians and DJs, the DR-01S is packed with organic percussion sounds and simple, versatile grooves that tastefully complement the unplugged experience. It’s an ideal companion for acoustic guitar and vocals, and just as powerful with ukulele, violin, piano, and other types of acoustic instruments.

The friendly interface on the DR-01S makes it easy to cater beats and variations to suit any style, while the onboard speaker provides high-quality sound that blends perfectly with acoustic instruments. And with battery-powered operation, you can take your rhythm partner everywhere you go. 

The Perfect Rhythm Partner for Unplugged Music
One of the great joys of acoustic music is that it’s simple and uncomplicated—you just grab your instrument and start playing. The DR-01S flows seamlessly with that relaxed unplugged vibe, offering a friendly panel interface, all-in-one design, and tasteful, understated grooves that enhance any acoustic music style without getting in the way. Via dedicated buttons, you can call up all sorts of beats and variations, layer up to seven instruments together to create your own unique rhythms, and save up to 50 favorites for later recall. 

Expressive Percussion Instruments and Grooves
The DR-01S takes full advantage of the acclaimed rhythm machine and sound development history of BOSS and its parent company Roland. A large variety of authentic acoustic percussion sounds are on board, including shakers, maracas, tambourines, congas, bongos, bells, cajon, and many more. 

Impressive Sound in a Compact Design
With its integrated audio system, the DR-01S produces warm, full sound that blends right in with the natural tones of your acoustic instruments. BOSS’s advanced approach combines an innovative cabinet design, custom speaker, and a high-efficiency amplifier to deliver impressive sound in a highly portable package. 

Hands-Free Control with Optional Footswitches
While you can access all DR-01S functions from the front panel, it’s often handy to perform some operations while keeping both hands on your instrument. And by connecting one or two optional footswitches, you can. There are a variety of assignable functions to choose from, including start/stop, tempo up/down, tap tempo, pattern variation, and many more.
