Basically, it's what you would expect. The sound is not as bad as a previous reviewer would have you think, though if you're looking for a faithful recreation of an acoustic piano sound, look elsewhere. I like a coupe of the synth-lead tones, especially the sine wave because it sometimes sounds like it is tuned to just intervals. However, my biggest disappointment is that the midi usb connection is not compatible with windows vista. I think you deserve to know that.

Flexibility is the Key

By Salescatcher

from Los Angeles, CA

The Casio CTK-720 keyboard is wonderful for those looking to learn music, the intermediate or professional musician. The options of a power adapter or batteries allows for anyone to play, anywhere. It offers a choice of fingering method or voice, making it easy for the beginner. For the intermediate, it has a great song/piano bank for those wishing to expand their horizons. The rhythm/tone banks are of a very good quality. Midi make it a valuable tool when using with the computer. This is an excellent portable because of it's flexibility. I recommend it highly.

Good for price

By kopguy

from Fremont, CA

The unit is certainly good for price even my 2 year old started banging on it.Casio though does not supply basic stuff like an ac adapter this is rather surprising for a company like Casio. Fortunatly I had one lying arround and could use it for CKT720.

Terrible sound

By Anonymous

from Undisclosed

Well it is a very inexpensive keyboard. The quality of manufacture seems OK for the price range. But the sound is terrible. The piano sounds are just pathetic. My kids used to have a $20 toy keyboard that sounded more like a real piano than this one does. I got it as a gift, and I only want it to learn on, but if I had heard it first I would never buy it.

Keys Please

Ask me a question

I own a Roland digital piano that sounds & plays great. I bought the Casio CTK-720 to have a second board, and for what I paid, I have no complaints. I'm constantly amazed at what I got for the price I paid. The instrument recently suffered a fall from quite a height with no damage or affect on the sound. Worth every penny.
