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. The Arpeggiator provides an expanded 150 different patterns and 40 arpeggio Voices. These easy-to-use professional features, along with its new black body, set this keyboard apart from others in its class.
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.
