WK-7500


TOKYO, September 6, 2010 — Casio Computer Co., Ltd. announced today the release of the WK-7500, a top-of-the-line electronic keyboard fully equipped with exciting functions for producing music and creating sounds, all packed into a single unit. With the WK-7500, musical performances and accompaniment can be saved as song data and stored in Standard MIDI File (SMF) format or as audio files.

The WK-7500 features a Song Sequencer offering 16 tracks plus one system track. On the system track, both the keyboard performance and the auto accompaniment are simultaneously recorded. Then, up to another 16 tracks of music played on the keyboard can be recorded. A Pattern Sequencer also allows users to create original accompaniment parts. Furthermore, the WK-7500’s Audio Recording / Playback Function enable sounds from an external microphone or other instrument to be recorded for playback, then simultaneously mixed with keyboard performances and the Song Sequencer for recording. Taken together, these functions unleash the user’s full creativity to make great music.

The WK-7500 is also loaded with a full range of functions for creating sounds, including a wide choice of Multiple Digital Effects—100 types of Digital Signal Processor(DSP) effects,* 10 reverb effects, and 5 chorus effects*—and a Tone Editor that allows users to set various parameters to make original tone patches.
* DSP and chorus effects cannot be used at the same time.

The WK-7500 is equipped with 800 diverse tones and 250 rhythms built-in. Included in the tones are 50 Drawbar Organ tones that can be adjusted using nine sliders that function as drawbars corresponding to certain ranges of overtones. Users can also change the speed of the rotary speaker effect and add percussion at the press of a button—making the enjoyment of performing come more and more alive.

Along with the WK-7500, a 61-key version with the same functions—the CTK 7000—is also being released.

Main Features of the WK-7500 and CTK-7000


Song Sequencer

The Song Sequencer offers 16 tracks plus one system track. The sequencer not only records keyboard performances in real time but can also be used as a step sequencer, allowing users to manually enter the length and pitch of notes. Output sounds can be changed for each tone after song data is recorded, and all standard editing functions are provided, including punch-in and punch-out for overdubbing musical passages, as well as quantizing functions. Completed recordings can be converted to Standard MIDI File (SMF) format and stored on an SD memory card.

Pattern Sequencer

Users can create patterns containing a maximum of eight tracks, and up to 100 patterns can be stored in memory. The Pattern Sequencer enables the creation of backing rhythms by selecting from the many built-in rhythms and organizing them together. Parameters such as the tone, volume level and reverb can also be adjusted.

Audio Recording / Playback Function

Accompaniment and sounds from the external inputs can be mixed and recorded, and then saved on an SD memory card for playback. In December of this year, Casio plans to provide software—downloadable from its website free of charge—to allow users to store data in .wav format on their computers.

Multiple Digital Effects

100 types of DSP effects,* 10 reverb effects, and 5 chorus effects* are built-in, and up to 100 original DSP effects can be created and stored in memory.
* DSP and chorus effects cannot be used at the same time.



Tone Editor

Up to 100 original tones can be created and stored in memory by changing any of the 800 built-in tones using parameters such as attack and release time, filter cutoff, vibrato, reverb, chorus, and DSP.

32-channel Mixer

Each channel can be independently adjusted for volume level, pan position, reverb send, and other parameters, and sounds from the external inputs can be included in the mix.
