Casio CT-X700 61-Keys Portable Keyboard, Bundle Set (CTX700 CTX 700): 

The CT-X Series comes with the AiX Sound Source, which can produce a wide range of sound qualities from powerful bass tones to clear high tones. The exceptional computing power of the high performance LSI reproduces the natural charm of acoustic instrument sounds, such as the agreeable change in tone when a piano key is struck, the sensation of a drum performance, or soaring strings. The high-speed digital signal processor is also applied for each sound type, such as melody, backing drum and bass, or organ. Even the standard ensemble for a keyboard delivers distinct sound for each instrument for an expressive performance.
