Boss DR-670 Dr. Rhythm Drum Machine

This compact and affordable drum machine incorporates the waveforms and patterns of the flagship DR-770, while adding features musicians have been asking for: velocity-sensitive pads, a new Bass part, a pad interface designed to emulate a bass guitar fretboard, footswitch control of start/stop and fill-ins, plus Roland's popular Direct Pattern Play function for triggering patterns "on the fly" from the drum pads.
