The CK series allows combining and editing these voices to create practical sounds.
[PARTS & VOICES]
The CK series sound engine is divided into 3 parts (Part A/B/C), allowing selection of voices for each part. Each part includes ON/OFF buttons and volume sliders for adjusting sound balance between parts, categorized for easy voice search.
[LIVE SET]

Up to 160 Live Set Sounds can be stored across 20 pages (8 sounds per page), accessible instantly using 8 buttons on the panel. Additionally, the CK series includes 80 preset Live Set Sounds for immediate use.

Instant Setup and Operation with One-to-One Interface
High-frequency functions and controllers used in live performances are all conveniently located on the front panel, adopting a "One-to-One" style where each controller is assigned to one function. This allows instant manipulation of sound settings (Live Sets) and real-time sound shaping with filters and effects even during performances. Moreover, equipped with drawbars reminiscent of vintage organs for creating desired organ sounds, supporting players in expressing their musical visions.

Built-in Speakers and Battery Operation for Play Anywhere Capability

By connecting the unit to a microphone or via Bluetooth with devices like smartphones, performances can be held anywhere, regardless of acoustic facilities. Furthermore, it supports battery operation, making it easy to carry and use in places where power sources or PA environments are not readily available.

Integration with External Devices such as Microphones and Smart Devices
Utilizing Live Set support functions, effects can be applied to audio signals from microphones or external sources during performances. Additionally, Bluetooth connectivity allows playback of audio from Bluetooth-enabled devices like smartphones, outputting sound through the built-in speakers or line-out. This feature supports a variety of uses, such as playing intro SEs, BGMs, or rhythm track sources based on user ideas.
[A/D Input]
As part of Live Set support, dedicated effects can be applied to audio signals from external inputs. By connecting a dynamic microphone, users can set vocal effects without needing an external mixer, enabling performances like solo acts or vocal & keyboard duos.
