This late 90's 88-Key Clavinova includes AWM (Advanced Wave Memory) and 32 Polyphony. This model is now discontinued. This unit has been well cared for and was a learning piano for our two daughters who played for several years but have long since discontinued music lessons. All electronic functions work, two small flaws noted in this linked Ponga picture, along with more detail: http://ponga.com/b12c6cc1bae4c5ff
