Piano-Focused Expression with the Freedom to Play Anywhere
The Yamaha CK88 combines an 88-key Graded Hammer Standard action with a complete stage-ready palette of piano, electric piano, organ and synthesizer sounds. Direct front-panel control, three-part performance architecture, built-in speakers and optional battery operation make it a remarkably versatile instrument for pianists performing, rehearsing, recording or creating away from a conventional setup.
Authentic Piano Feel, Complete Stage Sound
88-Key Graded Hammer Standard Action
The fully weighted GHS keyboard uses a heavier touch in the lower register and a lighter response toward the top, giving acoustic-piano parts a familiar, expressive foundation.
Premium Yamaha Piano Voices
Play sounds inspired by the Yamaha CFX, S700 and CF3 concert grands plus the character-rich U1 upright, alongside vintage reed, tine, Clavi and DX-style electric pianos.
Dedicated Organ Control
Five organ types, nine physical drawbars, rotary-speaker control, percussion and enhanced vibrato/chorus place expressive organ performance directly under your hands.
Three Independent Parts
Build sophisticated splits and layers from piano, organ, synth, bass, strings, brass and pad sounds, then balance and process each part from the front panel.
Hands-On Sound Shaping
Dedicated filter and envelope controls, Mono and Unison modes, Drive, dual insertion effects, master delay, reverb and three-band EQ encourage fast, musical editing.
Performance-Ready Recall and Control
Live Sets store complete panel configurations, while four-zone MIDI Master functionality integrates external modules, software instruments and larger keyboard rigs.
Full-Size Performance without a Fixed Location
Despite its 88 weighted keys, the CK88 weighs 13.1 kg and includes switchable stereo speakers for practice, writing, rehearsals and intimate performances. Eight AA batteries can provide up to 4.5 hours with rechargeable Ni-MH cells or up to 3 hours with alkaline batteries. Battery life varies with use; batteries are not included.

- Bluetooth audio input for wireless backing tracks where supported in the market

Frequently Asked Questions
How is the CK88 different from a conventional digital piano?
The CK88 provides a weighted 88-key action and strong piano sounds, but adds extensive stage-keyboard capabilities including drawbar organ control, synthesizer editing, three-part splits and layers, Live Sets, MIDI Master functions and expanded audio connectivity.
How is the CK88 different from the CK61?
The CK88 uses an 88-key Graded Hammer Standard action for a more piano-like response. The lighter CK61 uses a compact 61-key FSB action better suited to players prioritising portability and fast organ or synth technique. Their core sounds and performance features are otherwise closely aligned.
Can it operate without external speakers?
Yes. The CK88 has switchable stereo speakers powered by two 6 W amplifiers, suitable for personal practice, rehearsals and small-scale playing.
Can I connect a microphone or another instrument?
Yes. Stereo A/D inputs accept an external source and provide two dedicated effects. The incoming signal can also be included in audio sent through the USB interface.
Can the CK88 control external instruments?
Yes. Four-zone MIDI Master functionality, 5-pin MIDI In/Out and USB MIDI allow it to control compatible hardware and software instruments.
Is an AC adaptor included?
Yamaha specifies the PA-150B or an approved equivalent. Inclusion can vary by market and shipment, so please confirm the supplied accessories with YMS before purchase.
