Along with the standard digital piano features, the Korg SP-280 offers a “partner” mode that splits the keyboard into two identical parts for playing along with a teacher or friend, as well as a mode enabling you to layer two sounds. It comes with multiple sound types, ranging from strings to electric organ, and its 22-watt stereo speakers are powerful enough for a small gig. With a USB port, sustain pedal jack, two headphone outputs, and stereo audio output, the Korg SP-280 sports a versatile feature set for the modern keyboard player.
