UTILIZATION

General configuration so easy especially when you're used to Yamaha arranger.
Ideal to learn, to begin in the keyboard or confirmed.
Operation is very simple and intuitive. A great keyboard to start a child with anything other than a toy ridiculous.
This keyboard is also an excellent 49-key master keyboard thanks to its full MIDI implementation.
No editing sounds. The effects are nice.
I never had the manual in the hands and if I had it would have taken only the dust on the outside ......

OVERALL OPINION

Qualilté excellent sound quality manufacturing and blameless (Yamaha's reputation and its PSR is well established).
The best: the numeric keypad 0 to 9 and "+" button and "-" for selection and setting parameters easier and quickly accessible.
The least: the lack of velocity.
Owned 2 months, just out of curiosity because I did not know this model. Really surprising realism of a sound point of view! it has nothing to envy to its big brothers in 61 keys.
With the experience I would say that if you look a little easy to use arranger keyboard coupled with a 49-key keyboard controller effective model for you, especially if you have children who are interested in learning the keyboard it will be more educational and serious type Bontempi a toy ......
