Richer Harmonics & Stronger Resonance
DDP-400 has extended speaker cabinet, which lengthens the strings and enlarges the soundboard area. So the harmonics are richer and the resonance is stronger than ordinary digital pianos.
138 Tones & 128 Polyphony
DDP-400 is equipped with 128 voice polyphony, 138 tones (including 128 musical instrument sounds and 10 drum tones), 100 rhythm styles and 20 demo songs. So you can explore a variety of musical genres and playing styles. The Bluetooth allows you to learn lessons online or make demo recordings and music arrangement, via USB MIDI connection with computer.
