Why The Casio CTK-2100 Is A Top Seller

The Casio CTK-2100 is one of the top selling piano keyboards available for a good reason. This keyboard has 61 keys, not a full keyboard but enough to play almost anything a beginner or intermediate player would want.

It sounds better than many keyboards out there because of the AHL sound source. AHL stands for Acoustic & Highly-compressed Large-waveform and basically means that the sound source is pre-programmed with digital samples of acoustic musical instruments recorded using the most advanced digital technology. The AHL sound source is capable of reproducing all of the natural smoothness of the original waveform.
