Korg KDM-3 Digital Metronome With powerful performance features, a high-output onboard speaker, and a look that's reminiscent of your favorite mechanical metronome, the Korg KDM-3 is sure to please traditional and modern players alike. A wide tempo range (30–252 bpm), driven by 19 beat patterns and eight metronome sounds, gives players the foundation they need to practice jazz, rock, classical, and Latin music. Tap tempo lets players punch in their preferred playback speed, and LED indicators provide visual feedback for private practice sessions. An 1/8" headphone output delivers clean sound to your ears or into an amplification system for group rehearsals. BPM markings provide tempo ranges for tempo largo, adagio, allegro, and more.
