Casio WK 200: Hi, my name is Mike Martin, and I'm here to talk about the WK 200 from Casio. This is a 76-key music workstation, with 76 piano-style, touch-sensitive keys. It has 570 built-in tones and 180 rhythms. The WK 200 also features ΒΌ inch output, so you can connect it to a PA, keyboard amplifier, or other speaker system. That's of course on top of the built-in speakers on this product. It has USB, so you can connect it to your Mac or PC. A great big onboard display for utilizing the three-step lesson system. An absolutely complete package, and last but not least, it does have sampling through the MP3 input, on the back, you can plug-in your iPod or MP3 player and utilize its 10 seconds of sampling and incorporate those sounds into compositions that you created on the product. That's the WK 200, a 76-key workstation from Casio.
