The Alesis Prestige Artist 88-key digital piano is a full-featured digital piano with graded hammer-action keys and 30 incredibly realistic built-in sounds. This is the perfect substitute to owning a full-size acoustic piano, with premium multi-sampled voices, 256 max polyphony and a custom-voiced 50W micro-array speaker system that sounds full and brilliant regardless of room position. The lightweight Prestige Digital Piano is compact enough to play, store or bring it anywhere you'd like. An intuitive OLED screen and control panel make changing sounds and other settings a breeze. Lesson Mode divides the keyboard into two halves with the same pitch and voice, ideal for students to follow along with their piano teacher or to play a duet with another player. Record Mode lets you record and then listen back to your performance. Layer and Split modes, five selectable Reverb FX Types and an arpeggiator allow further sound shaping. For private practice, plug into either of the front-facing headphone jacks to automatically mute the speaker system.
