Rich Advanced Tones and Effects
A total of 400 Advanced Tones are programmed with DSP tones to make them richer and more powerful. Advanced tones like Stereo Piano and Tremolo Electric Piano enhance the Piano and Electric Piano tones to create a totally new sound. The WK-3800 includes 50 realistic drawbar organ tones that can be controlled using nine digital drawbars. You can also select percussion or key click, and even edit the parameters of preset tone and save up to 100 original tones in user tone memory. Edit built-in sounds to produce your own original creations. Up to 120 of your own sounds can be stored in memory for recall, just like the built-in tones. A collection of powerful effects, such as DSP, reverb, chorus, and more, give you total control over the type of sound you want. You can change the parameters of an effect to create your own, original effects. A 4-band equalizer is also included.

166 Preset Rhythms + 16 User Rhythms
The WK-3800 includes a selection of 166 rhythms with accompaniments for everything from rock to pop and jazz. You can also transfer accompaniment data from your computer and store up to 16 of them as user rhythms in keyboard memory. With the WK-3800's song memory, you can record up to six parts along with their tone, volume, pan position, and other parameters for later playback.

Auto Accompaniment
Simply play a chord and the corresponding rhythm, and the WK-3800 plays bass and chord parts automatically. One-touch Preset instantly recalls the most suitable tone and tempo settings to match the rhythm you are using.

Big, Information-packed Display
A big built-in display shows chord names, tempo setting, keyboard information, staff notation of notes played and more for full support of all your keyboard play. A built-in backlight keeps the display easy to read, even in total darkness.

General MIDI Compatibility
The General MIDI tones of this keyboard let you connect to a personal computer to enjoy "desktop music" capabilities. This keyboard can be used as a desktop music input device or sound source, and it's just the thing for playback of commercially available pre-recorded General MIDI music software.

Flash Memory
The WK-3800's built-in Flash memory lets you expand your selection of tones and rhythms by downloading data from the Casio music website, or by the CD-ROM that comes bundled with the keyboard. You can also store up to 200 SMF format music files for playback.

Many of the keyboardists here at Sweetwater have fond memories of Casio that go all the way back to when we first started playing, and that's often kept us coming back for decades. Today, we're happy to point players to Casio keyboards, no matter how long they've been playing - even if they've never played at all. In fact, we've set up many beginners with Casio LK series Lighted-key models, and they've regularly raved about how easy these keyboards make learning. Likewise, several of the solo performers at Sweetwater swear by their fully loaded Privia and other advanced lines, which provide top-notch accompaniment and more. And if you stop by the Sweetwater Piano Showroom, we'll be happy to show you the latest Casio home piano - all providing amazing value and style.
