BOSS DR-01S Rhythm Partner Organic Groove Machine and Speaker The DR-01S features a powerful integrated sound system, and comes equipped with ready-to-play rhythm patterns that complement unplugged acoustic instruments

Compact, battery-powered, and simple to use, the go-anywhere DR-01S makes playing acoustic music even more enjoyable and inspiring.    Unlike other rhythm machines that are designed for electronic and pop music applications, the DR-01S is a unique product specifically designed for acoustic music

Backed by decades of percussion development by BOSS and Roland, the DR-01S contains a wide variety of organic acoustic sounds derived from high-end products

Via an intuitive interface, DR-01S users can access simple patterns and variations that are optimized for acoustic music styles

It’s also possible to add or subtract instruments like shaker, tambourine, bongos, congas, and more on the fly

Dedicated buttons are on hand to quickly adjust volume and tempo, and to add a count-in before the accompaniment starts

The DR-01S also includes a standard metronome for basic music practice

The DR-01S is equipped with a sophisticated audio system that produces big, full sound from a small footprint

An Aux In jack allows users to play backing music from a smartphone or other device, while a Line Out jack enables connection to a larger sound system

The DR-01S also supports optional footswitches for start/stop, tap tempo, and triggering sounds.
