The Yamaha CP-70 is an electric piano used by Dr Fink and Prince. Dr Fink played one live on the Controversy, 1999 and Purple Rain tours and it can be heard on the song Purple Rain. Prince also had one in his home studio, and it can be heard on the Piano & A Microphone album.
It is similar to the Yamaha CP-80, also used by Prince, and has actual strings amplified by a pickup.
