Add incredible-sounding drums to your music! Dr. Rhythm's loaded with acoustic and electronic drum kits, as well as a selection of bass sounds. Great for jamming, the DR-3's Rhythm Progressions and multiple variations make it easy to create a realistic-sounding drum track for any style of music. The Total Sound Control (TSC) feature allows you to tweak your kits to perfection.
The Rhythm Progressions feature lets you choose from 100 preset styles and use the 8 panel buttons to switch between different sections of your song. Up to 3 variations can be selected for each Intro, Verse, Fill, and Ending.
TSC lets you change the sound of a drum kit with specialized effects. The Sound Shape function can be used to adjust the 3-band compression and 3-band parametric EQ, or add some spaciousness with the Ambiance effect. An optional footswitch can be used to control anything from Intro/Start and Ending/Stop to Verse Change, Variation On/Off, Loop On/Off and more. Battery power lets you take the DR-3 just about anywhere.
