+: Pitch bend and modulation
+: Pedal close to a real piano

-: No support for partition
-: No speaker (see Yamaha CP300)

UTILIZATION

The touch keyboard is very good. It attempts to replicate the best realism of a true piano feel heavier in the bass and lighter in the treble. Obviously it's not a real piano, but the feeling is very close game. The finish is very good keyboard, Yamaha's reputation is second to none. There are three sensitivity curves (soft, medium, hard) for adjusting the touch.

In comparison with other M-Audio Keystation 88, Fatar, CME ... the quality of this keyboard is not subject to appeal through the reviews on the Internet.

The manual is easy to use. Apart from a few points (management office), use of the manual is necessary. Otherwise the system is extremely intuitive.
<span style="text-decoration: underline;">For / Against:</span>

+: Heavy touch
+: Finish the keyboard
+: Intuitive

-: Some functions are difficult to use without the manual

SOUNDS

The sound quality is generally uneven. As a keyboard, the focus is on the piano. This is very good, very well reproduced. The bass are deep, the sustain is realistic. The main sound is very good. There are different versions of the piano (classical, electric, compressed ...).

Then, some sounds are goods such as harpsichord, choirs, electric piano ... Other really means: strings, guitar.

This keyboard has a set of very interesting effects:
- Reverb (hall, stage, room)
- Brilliant sound
- Split mode to split the keyboard with two instruments
- Dual mode to overlay two instruments
<span style="text-decoration: underline;">For / Against:</span>

+: Very good quality piano sound
+: Well-balanced and realistic reverb

-: Uneven quality of some sounds (eg strings)
-: Sustain applied to the two sounds at once in dual mode. Piano + strings, the strings "drool" so so unpleasant.
-: We must reconfigure the effects at each turning off the keyboard. The automatic backup function saves the settings as they are when the power is turned off. This point is poorly thought out. Why not save the default settings changed?

OVERALL OPINION

My choice was not complex. I wanted:
- A 88-key keyboard with a touch heavy, with sound internal
- Used as a keyboard as a keyboard (noon rolls ...)
- A renowned professional keyboard

The only keyboard that met these criteria was the Yamaha for:

+: Trust in the brand
+: The quality of touch
+: The quality of his piano

-: High price (1200 € on Thomann)
-: No speakers

When you buy a keyboard, a keyboard is sought precisely correct. So I removed the M-Audio Keystation keyboard for its uneven quality and some other brands (CME Fatar ...) to the views of opinion sharply divided.

The price is not negligible, but the quality is by appointment. There was no nasty surprises. It's pro, it works, it sounds good. In short, I will not hesitate again to make the election again.
