The PSR-E423 offers several innovative features. The basic features for learning to play — like the Yamaha Portable Grand and Yamaha Education Suite — and features for when it’s time to perform, like synthesizer Control Knobs for real-time control of filter, effects, sound envelope and Style tempo.

Control Knobs, Appreciator and Pitch Bend

Most of the features of the PSR-E423 have been enhanced over its predecessor. Two control knobs provide real-time control for filtering the main melody tone, and changing the tempo of the arpeggio just like an analog synthesizer. The Pitch Bend wheel brings Voices like the Sax and Trumpet to life.

Improved Arpeggio Function

Tap into instant inspiration with the Arpeggio function which has been improved for smoother playability. New hold mode and allocated key-range will free your hands for playing with both hands. It provides an expanded150 patterns that automatically generate even more useful phrases that change depending on the notes and chords you play.

A Variety of New Dynamic Voices

Dynamic Voices usually found on high-end workstations, are now on the new PSR-E423. There are two different waveforms that change depending on how hard you play the keyboard, this allows more expression on Voices such as overdriven or nylon guitar. High quality Voices, from acoustic instruments to electric sounds, have been expanded to 700 varieties. All of these high-quality Voices sound better through 2-way speakers.

Wider World Content and 174 Varieties of Styles with Auto-backing Mode

Auto-backing Mode Arabic, Indian and Chinese content has been added to Styles, Rhythm and Voices. With our high-quality Styles and Voices, you’ll sound like you have a professional backing band behind you.
