The Versatile and Professional Dr. Beat

More Info

Better Beats, Better Practice

The Note Mixing function allows you to instantly create a variety of beats by adjusting the levels of five different note values. Front-panel sliders, buttons, and a large rotary dial provide instant, hands-on access to edit parameters. Select four different click sounds, including a human voice-counting sound that will help you know your place in the bar. The DB-90 is also equipped with realistic PCM drum patterns, for developing your accuracy and rhythmic feel effectively.

Plug Into Rhythm Coach

Expand your rhythmic horizons with Rhythm Coach. This innovative follow-along feature has four training modes to help build your accuracy, speed, and endurance. With the DB-90’s onboard microphone, you can use the Rhythm Coach functions with acoustic drums, or plug a Roland V-Pad into the Trigger input. Play along, and chart your progress.

Many Uses

Drummers can connect to the DB-90 via Roland V-Pads or the internal microphone. Guitarist and bassist can directly plug into the DB-90 without any other gear required, and monitor via connected headphones — practically any type of instrumentalist can benefit from the DB-90’s features. And for those who wish to sync to an external sequencer for more elaborate accompaniment, they can do so with the DB-90’s MIDI input. This stage-oriented feature is especially useful for drummers.
