‌Take your sound where it’s never been before. Anywhere.

CK turns everywhere into a stage or studio with intuitive controls, built-in speakers, and all the sounds you need to create your own sound.

SOUND

CK combines the sounds of the Yamaha CP Stage Piano with the organ and synth focused YC Stage Keyboard to give you a totally new sonic palette. All with an intuitive interface that lets you focus on the music, not the menus. You’ll have piano, electric pianos, strings and brass plus a dedicated organ section and modern synth sounds. Onboard special effects to make it your own. There’s even Analog to Digital (A/D) Input to plug in a mic or another instrument, apply effects and record directly to your laptop. Not to mention CK has built-in speakers and batteries to take your new sound to new places. The options are nearly endless.

PIANOS, EP & KEYS - CK features piano sounds from three legendary Yamaha grands: the CFX, S700 and CF3, plus the character-rich U1 upright piano from the Yamaha YC Series. “Digi Piano” sounds let you get your 90s dance party on. There’s also a selection of vintage electric piano sounds in both the reed and tine style, funky Clavi sounds and the classic 80s DX7-style FM electric pianos Yamaha helped make famous. You’ll have all the keyboard sounds you need to bring down the house, arena or backyard barbecue.

ORGAN - When it comes to organ, the versatile CK is all about options. Classic 60s surf rock? Check. Soulful R&B? Check. Gospel and everything in between? Amen. CK has a dedicated organ section based on the Yamaha reface YC mobile mini keyboard featuring five different organ types, rotary speaker effect, percussion and a newly enhanced vibrato/chorus. You get nine dedicated drawbars with controls for the rotary speaker, percussion and a vibrato/chorus section.

SYNTHS - CK gives you a variety of complex synth sounds without the complex menus. You get analog style pads, leads and basses, synth brass, strings and pads. Even synth bells and textures to add to your synth sound palette. All with modern synth controls to tweak your sound without menu diving. Elegant filter and envelope generator (EG) controls to shape the tone and amplitude of all of them. Mono mode with panel switch and customization features that are great for synth leads and basses. Unison mode with panel switch, three modes and deeper adjustments. Make massive sounding synths for stabs, pads, leads, basses or anything you can imagine.

EFFECTS - CK effects make it easy to turn its sounds into your sound. It starts with three dedicated effects processors: Drive, Effects 1 and Effects 2 plus an A/D Input with two dedicated Effects.

Drive features five types of overdrive and distortion to add edge to your sound.

Effects 1 and 2 gives you modulation effects like Chorus, Flanger and Phaser. Time-based effects like Delay and Reverb plus Wah, (even more) Drive, Tremolo and experimental synth effects such as Ring Modulation, Slicer, Lo-Fi, and more. Not to mention EQ. With 36 effects in all, it’s like having a built-in, customizable guitar pedal board.

Master Delay lets you choose from four different delay effects including Tempo Delay.

Master Reverb has three different reverb settings to put your sound in the right space. Both Master Delay and Master Reverb have their own send level from each of the three CK parts and A/D Input.

Then finalize the tone of your sound with Master EQ. Plug a mic or instrument into the A/D inputs, apply effects and hear the resulting sound through the CK’s speakers or outputs. You can even record anything plugged into the A/D input to your computer via the built-in USB audio interface.

THREE PARTS - CK lets you split, layer, mix and process all from the front panel. Making it easy to create with a nearly endless combination of sounds. Split bass and piano. Layer organ with strings. Experiment with modern synth sounds. CK gives you three parts that let the music go wherever you want.

A/D INPUT - Analog to Digital (A/D) Inputs let you apply two dedicated effects to the audio and store them to a LIVE SET.

CONTROL - CK features an intuitive, 1 to 1 interface that gives you the freedom to explore your sound. Everything, from dedicated Organ controls to Synth and Effects controls, is designed to keep you making music instead of diving into menus.

KEYBOARD ACTION - The CK Series has two different keyboard actions for different kinds of players.

CK61 features the new 61-key “FSB” or “Future System Basic” action, inspired by the famed “FS” or “Future System” action that was originally developed for Electone organs like the legendary FX-1. In the spirit of the original “FS” action, FSB uses a completely new structure. This action features a heavier initial key resistance and increased key travel for a wider range of expression and stability. This action is great for keyboardists playing organ, synths, strings and more, and provides piano and electric pianos with a dynamic, expressive response.

CK88 features Graded Hammer Standard (GHS), 88-key, weighted and graded action to recreate the feeling of playing a Yamaha grand piano, without ever having to call the piano movers.

UI - The intuitive User Interface lets you dive into the music, not the menu and features Dedicated Category buttons that make it easy to find the sound you’re looking for.

FILTER & EG - CK Filter and Envelope Generator (EG) feature dedicated controls for the most commonly-used synth parameters and a dedicated bypass button to quickly return to the default state. You have total control to shape your sound.

LIVE SET - LIVE SETS store and recall the exact settings for anything on the front panel including your splits, layers and special effects. It also stores and recalls features such as A/D Input setting, sample playback and LED light color.

MIDI MASTER - A four-zone controller connects with your external MIDI devices to turn CK into a full-fledged MIDI controller with your DAW or master keyboard in your MIDI rig. Which means you get four additional sounds at your fingertips with complete control of the splits, octave adjustments, patch changes and more.
