The Yamaha PSR-EW310 is a 76-key portable keyboard intended for intermediate and advanced players looking for a broad selection of high-quality acoustic and synth instrument sounds with realistic articulations and DSP effects. It offers a set of easy-to-use features including an arpeggiator, built-in songs and lessons, auto accompaniment styles, MIDI song recorder, USB audio interface, and on-board speakers—great for enjoying playing in a variety of musical genres, whether at home or on the go.

The PSR-EW310's extended 76-key keybed permits you to perform more complex piano pieces than you could on a 61-key keyboard. Touch sensitivity senses hard and soft playing and matches the dynamics of each key stroke to accurately capture every nuance of your playing style.

The keyboard uses AWM sampling technology to provide 622 inspiring sounds including strings, guitars, brass, saxophones, and drums. A dedicated button lets you quickly switch to a rich Grand Piano sound. To deliver even more realistic and authentic performances, a host of Super Articulation Lite Voices reproduce the subtle nuances of stringed instruments, such as the cello and mandolin, which are typically difficult to emulate on a keyboard instrument.

The built-in 205 auto-accompaniment styles provide real-time band backing tracks based on the chords you play and in a variety of musical genres from around the world, such as pop, jazz, R&B, salsa, and more. Smart Chord technology allows you to play complex chord voicings with just one finger, while the Arpeggio function further expands the keyboard's versatility. Jam with the band and use the 2-track MIDI song recorder to capture your performance and play it back later.

The Keys to Success mode includes learning techniques to help you learn how to play the 154 built-in songs-each with its own digital score. You can select just the key phrases of the song and practice them one by one. The three-part lesson functions make learning easier by breaking performances down into left- and right-hand parts and then putting them together. Chord progression lessons are onboard, while the Touch Tutor lesson mode tracks how hard you hit the keys, reinforcing proper dynamics technique. Duo Mode can be engaged to split the keyboard in half, a smart and practical way to play with a partner or for one person to teach another how to play.

A built-in speaker system delivers a clear sound, while the headphone output provides for private practice or playing. The 3.5mm aux input lets you connect your phone/tablet or music player and play along with your favorite songs. You can also use the Melody-Suppressor function to practice the melody part along with the audio playback.

The PSR-EW310's USB to Host port enables you to send USB MIDI and USB audio signals straight into your computer/DAW or smartphone for recording your music and performances.

Compact and lightweight, the PSR-EW310 is very portable. It runs on 6 AA batteries (available separately) or can be powered from the included PA-130 AC adapter.
