I have owned the CASIO CGP-700 since 2016. I was aware that the piano sound was not as realistic as the PX-360 or PX-870 that uses the chip with the AiR processor. However, when I tested it before buying it I liked the piano sound and thought the tradeoff was a good one considering all the other instrumental and effects features.
Fortunately my unit didn't have the same flaws that SNT reported on his instrument. However, there is one negative experience I wish to report. The keyboard in simulating an acoustic piano action is very noisy. When I use it with my headphones on the clacking noise drives my wife crazy. It defeats one of the reasons I got this instrument. Also, when I record video of me playing, these keyboard clacking sounds do get recoded. I would have to place my iPhone at a distance to minimize these sounds. I did find a work around.
I hooked up an iRig Stream that allows me to record the analog sound of the piano directly while recording the video, thereby eliminating extraneous noises. The overall sound quality is also excellent this way. I can use headphones or not, as the situation warrants.
After a a few hours heavy practicing, it is fun to jam with myself using the auto accompaniment features that are built in.
Let's face it, the CGP-700 is not perfect. There are other digital pianos that sound better. But not my much. It provides features and benefits that would cost much more with other manufacturers. Hence, I highly recommend the CASIO CGP-700 for beginners as well as more advanced musicians.
The demo pieces for promoting this instrument that CASIO provides built in sound simply amazing. I am looking for MIDI files created specifically for the CASIO CGP-700 by experts so that I can enjoy listening to the sounds that others create. If you know where I can find these, please let me know. The genre can be pop, jazz, latin or Classical.
Thanks!
