ABOUT POLYPHONY
The CP piano is capable of playing up to 96 notes simultaneously (96-note
polyphony). When playing in dual mode or when playing the stereo piano
sound, the polyphony will be reduced by half since the piano has to produce
two sounds for each note.
(6) Reverb
-REVERB adds reverberation to the sound simulating the acoustic
environment of a recital room or concert hall.

Room, Large Room, Medium Hall, Large Hall and Plate.
