Attack and release time, cut off, vibrato, reverb, chorus and DSP can be adjusted based on your preferences.


Casio continues the tradition or providing “class compliant” USB connectivity on Workstation digital pianos. This allows Casio Workstation digital pianos to be used with Mac or Windows computers without the need for downloading drivers. Class Compliant USB MIDI also allows Workstation digital pianos to be used as a controller for the Apple iPad simply by using Apple’s Camera Connection Kit.


The WK-6600 offers 48 notes of polyphony so you don’t have to worry about dropping notes. Using the sustain pedal for multiple notes, playing big chords, adding rhythms and layering sounds can deplete the polyphony memory quickly resulting in dropped notes. When searching for a keyboard, take the amount of polyphony into consideration.

Preset Rhythms

Casio’s WK-6600 includes 210 preset plus 10 user-created rhythms, which is more than comparable models. Additional rhythms expand your music composition, creativity and fun.

Multiple Digital Effects

A wide range of built-in effects include 10 reverbs, 5 choruses and 100 DSP types. You can create your own DSP effects and store up to 100 unique styles.


The WK-6600 can store 4 sets & 8 banks for a total of 32 set ups. The simplicity of the registration process makes it a great feature for live performances.
