Product Description

Amazon.com Product Description

The Casio CTK-671 Portable Keyboard features 61 full-size keys, 32-note polyphony, and 348 tones. Built-in 2.5-watt per channel stereo speakers give you good sound quality, and a headphone jack and stereo lineout (to attach the keyboard to a home stereo) give you the volume options you need for big performances or late-night practice.

With the keyboard you get 128 general MIDI, 100 face panel sounds, 100 variations and 10 drum sets ready-to-use. Using the synthesizer functions, you can create and store 10 of your own sounds. Simultaneously use up to four effects, such as reverb or chorus, to produce your perfect sound. The 100 rhythm patterns give you everything you need to start making music.

Casio's Internet Data Expansion system lets you download new sounds, patterns, songs, and keyboard settings over MIDI from Casio's Web site.

Other features include three-song/six-track recording with real-time or editable step time, six drum pads, a pitch bend wheel, sustain pedal jack, and a backlit LCD. The LCD displays selection and status of tone, rhythm, mixer, keyboard functions, and tempo for complete control.

The CTK-671 operates with an optional AD-5 AC adapter or D batteries.

2.0 out of 5 stars Decent sound, terrible support, useless for many purposes, January 1, 2003

By 

"mykea" (Mason, Ohio United States) - See all my reviews

This review is from: 61 Key, 5 Octave Keyboard with Sound Generator, Internet Expansion and TouchSensitive Keys (Electronics)

I am a bassist, guitarist, and vocalist working on my own project.

I did not have the money to throw into a Korg, Kurzweil, Roland, or Yamaha board. All I needed a keyboard/synth for was drum sounds and some keyboard/synth fill in. At first, this seemed like the model for me..

The touch sensitivity is nice.. most of the sounds are pretty decent, if not you can make all sorts of adjustments to just about anything for any tone... except the 'raindrops' tone, a common favorite on most keyboards/synths.. the raindrops tone for the Casio is a cheesy video game sound effect.

Otherwise, the sound and sound possibilities were surprisingly decent.

That is where the good review ends. 6 songs is not a lot of storage if you actually plan to compose with this thing.. no floppy. However you can save songs to your comp, and load songs from your comp to the keyboard.. if you have a good laptop and want to take it everywhere the keyboard goes, then this is not as much of a concern.

Don't buy it if you plan to use it with Cakewalk.. Casio does not provide the .ins (instrument definitions) file for it, and the manual is useless for creating your own. It works terribly with Cakewalk (and I would imagine other MIDI devices) for this reason.

If you just want to play, and never record anything, then this is the instrument for you, otherwise, go for something a bit more expensive. Do not go Casio though.. At present there are little to no .ins files for Casio boards anywhere on the web.

Also, it is certainly not an instrument to take on the road, partly for the limited storage, partly for its innability to interact with other MIDI devices to the extent it could and should be able to, and partly because it is very lightweight and flimsy, don't sneeze in its direction..

.. Look at the price, ask yourself if you can wait a while longer and buy something that is even just a little bit more expensive.. such as a Yamaha for a hundred or two more.

If you think it will help you on your home project... not unless you want to record and flatten to analog from track to track, or program everything into the keyboard and record analog.

5.0 out of 5 stars Excellent value for touch sensitivity, very good sound, February 9, 2007

By 

Brian B. "Guitarist, learning piano" - See all my reviews

This review is from: 61 Key, 5 Octave Keyboard with Sound Generator, Internet Expansion and TouchSensitive Keys (Electronics)

Love this keyboard! The touch sensitivity is easily worth any perceived compromises in sound quality compared to Yamaha or other comparably-priced products. The button layout & functionality is comprehensive without being overwhelming. Manual is good--and on-line. Backlit display is also a plus, as is the midi connectivity & modest recording capability. Sound quality of pianos & organs is especially good. Not sure if that quality would be maintained direct through a p.a., but it is certainly of high enough quality for home recording & use in small clubs. Sounds are very tweakable, and the advanced tones are for the most part immediately useful. Guitar tones are good. Obviously more expression is possible playing an actual guitar, but here again the touch feature helps--if you hit the keys hard, you get a much more dynamic response than from playing lightly. Sustain pedal is very useful for not much money. Back is tapped for two retention bolts for use on a stand, but I would be more comfortable gigging with it in a flight case of some sort. Casio calls this keyboard "high-grade," and that's an accurate assessment--it's much better than most keyboards in the $100-200 price range, and is definitely not a toy but a real, expressive musical instrument.
