The P-S500 models two legendary concert grand pianos: the Yamaha CFX and the Bösendorfer Imperial. Yamaha's Graded Hammer Standard (GHS) keyboard with 88 weighted keys and Virtual Resonance Modeling (VRM) technology provides an authentic piano-playing experience. A variety of instrument sounds are provided to spark your creativity including classic synthesizers, strings, percussion and drums, guitars, and more. Using the 1/4" input you can connect a microphone to sing along while you play and hear your voice through the instrument's speakers. You can also record your performances and musical ideas with studio-quality audio that gets saved directly to your smart device for easy sharing.
