The Casio CTK-6600 Portable Keyboard's Song Sequencer provides 16 tracks plus one system track that supports recording of up to five songs and a total of approximately 12,000 notes.  A 32-channel Mixer with button operation can be used for individual simultaneous adjustment of volume, pan, reverb send, and other parameters. The Rhythm Editor lets you combine instrument parts from multiple built-in rhythms, turn individual instrument parts on or off, and adjust volume, pan, reverb, and other parameters to create your own original rhythms. You can even store up to 10 original rhythms in memory for instant recall whenever you need them.

Built-in digital effects include reverb (10 types), chorus (5 types), and DSP (100 types using 46 effect types including delay, phaser, flanger, wah, rotary, and more).Plus, you can create original DSP effects and store up to 100 original types in memory for later recall. The equalizer incorporates five selectable frequency characteristics,including “Bright” for a lively sound emphasizing the treble range and “Powerful” with a stress on volume.  

A simple operation saves the current setup, including tone, rhythm, and other settings for instant recall when you need them. 4 sets x 8 banks for 32 setups. Recalling a registration instantly changes the digital keyboard's setup, making this a great tool for live stage performances. Tone Editor can be used to adjust attack time, release time, cut off, vibrato, reverb, chorus, DSP, and other parameters as desired. You can create distinctively original tones for performances and music creation sessions. Song sequencer, tone editor, and other data can be saved to an SD or SDHC memory card. SMF (Standard MIDI File) data stored on an SD or SDHC memory card can be played back on the digital keyboard.

Line out terminals (L/MONO, R) for connection of the mixer of a stage PA system or other devices, a MIC IN terminal for connection of a musical instrument or microphone, an audio in terminal (AUDIO IN) for audio device input that can be output through the speakers, and more.  The USB port provides easy computer and MIDI send/receive connection. It also enables quick and simple transfer of song sequencer, pattern sequencer, tone editor and other data, as well as audio data recorded to an SD memory card from an audio device between the digital keyboard and a computer.

I'd it it again.


Sounds good. I'm still Learning my way around it. I'm looking forward to finding out all its various sounds.



Decent keyboard at a budget price.


Nice keyboard for the price. The keys and the key bed feel quality the sound quality is also very good. The only downside is as with most casio's there is a small learning curve to figure out how to do everything other companies seem more user friendly but over all a great keyboard for the money



Glad I got it.


Good quality, nice sounds.



Best keyboard in the price range.


If you need a lot of good sounds for a low price, this is the keyboard to buy. Incredible variety of features. Lots of programming and recording ability. The keys are not weighted, but are piano-style, which is great for fast synth work. Only one negative would be the speakers are a bit small and have a poor bass response.



Good buy


perfect first keyboard for my son to work with. Great price for what you get as well. Would be nice if it came with the adapter for the headphones or the pedal.



Love this.


I taught myself how to play the piano on a piano while staying at a friend's house. I enjoyed it so much I decided I couldn't give it up. But I live in a relatively small apartment. So I got this keyboard. I have it facing out to big view window and just love it. I can tune up any aspect of the keys. It is a winner.

Great For Start Up Studio !


I use this to produce music in my home studio. I have owned big name equipment before and sold it all. Then I wanted to rebuild my studio with low cost budget quality gear. This baby is just right ! The quality is top notch ! Casio you are the best ! I can make a beat Idea with out having to power up the computer at all. It looks expensive and it can hang with the big names. sleek cool design. the sounds are very good. It hooks up and control my DAW with no problem. Keys feel great. I can make beats but it don't have the semless loop feature that the 7600 has but that is okay. I just record str8 from the keyboard into my daw and loop like that with no problem! Saved $150 bucks and took that money and got me a recorder interface instead ! So it is a win win ! A very smart choice for producers on a tight budget !




Great keyboard...


...for anyone at any skill level.
