Williams Legato is an affordable digital piano with 88 semi-weighted keys, five great sounds (piano, electric piano, organ, synth, and bass) and built-in speakers. It also features split/layer function (to combine sounds) and a built-in metronome. This ultra-portable piano is perfect for performing and practicing. VoicesThe Legato piano has 5 built-in voices. Each voice may be selected one at a time. They can be layered to produce two voices at once, or assigned to the left or right hands in the split mode. Voices include: Piano, Electric Piano, Organ, Synth and Bass.Split ModeSplit Mode allows the keyboard to be divided into two sections so that different voices may be played with the left and right hands. The volume may be independently adjusted for each voice, the Split Point (the highest note played with the left hand) may be adjusted and the Split Voice may be changed as desired.Reverb and Chorus ButtonsThe Reverb and Chorus effects may be applied to each voice individually and will be retained even when the power is turned off. To apply either effect, press either button. The button will light and the effect will be heard when the piano is played. To turn off the effect, press the button of the desired effect again and the LED light will go off.Note: This keyboard operates on batteries or with a power supply, but it ships with neither. We enthusiastically recommend the Williams ESS1 Essentials Pack for the Legato Digital Piano, which comes with a power supply, sustain pedal and pair of headphones.
