With authentic piano, organ and synth sounds, intuitive controls and built-in speakers, the lightweight CK61 makes everywhere a stage or studio.
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.
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.
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.
