Special Features

Sequencer and mixer functions for total musical creation support

Song Sequencer

The Song Sequencer provides 16 tracks plus one system track that supports recording of up to five songs and a total of approximately 12,000 notes. Each individual musical instrument part can be recorded to a different track for real multi-track recording capabilities. A full selection of editing tools include event insert, event delete, event copy, quantize, a locator feature for selecting the range of notes to be edited, and more. A step recording function also lets you input notes by specifying the length and pitch. Completed recordings can be converted to SMF (Standard MIDI File) format and stored to an SD memory card.

Song Sequencer

32-channel Mixer

Button operation can be used for individual simultaneous adjustment of volume, pan, reverb send, and other parameters. Sound input from an external source via the MIC IN terminal can also be adjusted as desired.

Rhythm Editor

Rhythm Editor lets you combine instrument parts from multiple built-in rhythms, turn individual instrument parts on or off, and adjust volume, pan, reverb, and other parameters to create your own original rhythms. You can even create original rhythms for NORMAL, FILL IN, INTRO, and ENDING accompaniment patterns. You can store up to 10 original rhythms in memory for instant recall whenever you need them.

Effector and everything else you need to create exactly the sound you want

Multiple Digital Effects

Built-in effects include reverb (10 types), chorus (5 types), and DSP (100 types using 46 effect types including delay, phaser, flanger, wah, rotary, and more). You can apply different effects to a tone to create exactly the sound you want. By adjusting the parameters of the DSP effect types, you can create original DSP effects and store up to 100 original types in memory for later recall.

  • * DSP and chorus cannot be used simultaneously.


Incorporates five selectable frequency characteristics,including “Bright” for a lively sound emphasizing the treble range and “Powerful” with a stress on volume.


A simple operation saves the current setup, including tone, rhythm, and other settings for instant recall when you need them. * You even can save tones to which effector effects are being applied. Recalling a registration instantly changes the digital keyboard’s setup, making this a great tool for live stage performances.

  • * WK-6600: 4 sets x 8 banks for 32 setups

Tone Editor

Tone Editor can be used to adjust attack time, release time, cut off, vibrato, reverb, chorus, DSP, and other parameters as desired. You can create distinctively original tones for performances and music creation sessions.


With the arpeggiator, you can play various arpeggios and other phrases automatically by simply pressing keys on the keyboard. You can select from 150 different arpeggiato types, including playing arpeggios from a fingered chord, guitar phrases, and more.
