The Casio WK200 Personal Keyboard offers great tones, sampling, and lessons in one great keyboard! Casio is showing how much they can fit in to this keyboard while offering at a price that makes it impossible to turn down. The New AHL sound source (Acoustic & Highly-compressed Large-waveform) features all built-in tones, including piano and acoustic instrument tones, now sound better than ever before! 48-tone maximum polyphony provides plenty of margin to minimize the chance of notes being dropped when tones are layered and when playing with Auto Accompaniment. The Sampling function allows the user to sample a sound and then play it on the keyboard! You can create sound effects for a party or other events, or use sounds to compose music. Sample sound from an audio device plugged into the Audio In jack or from a microphone plugged into the microphone jack! The WK200's touch response let's you add delicate nuances to notes by varying how much pressure you apply to keyboard's keys. Need a challenge? Test your response with an exercise that is just like playing a game! Music Challenge tests your reaction speed by requiring you to press the keys indicated by the on-screen keyboard guide in time with the Auto Accompaniment tempo using the correct fingers indicated by the on-screen fingering guide. Step Up Lessons provides pieces that are divided into short, easy-to-master phrases making it easy for just about anyone to learn to play. After you master a phrase you advance to the next one. With this new lesson function, you keep building up your collection of mastered phrases and soon you are able to play the entire song. The Voice Fingering Guide senses if you are having problems, and will help you by calling out finger numbers in a simulated human voice. The WK200 contains a 152 Song Bank worth of tunes, including 50 Exercise phrases. This package comes bundled with headphones, single x-braced keyboard stand, and a power supply.
