no output to, connectors at the back instead of being on the left side, the p120 and p90.
no two headphone outputs and no input as to the p 250 and CP300.

UTILIZATION

The touch remains the same as the p120 and p90, it's very good
volume control is a button that you turn as the P250, the possibility of
settle the volumes of two sounds separately a split or layer on the front of CP33 is practical, while the p120 or p90 was more complicated.

the adjustment of the brilliance of the sound is also more efficient than the potentiometer on the p90
and p120

SOUNDS

I find the opinion of the person before very difficult, but it's true.
a digital piano does not sound like a real piano. Sometimes it sounds better and sometimes worse. It all depends on what you play and where we play.
in short, to choose the CP33 is what is best for the moment at Yamaha CP33, p90, p120 here's the top three (remaining within the portable models).

OVERALL OPINION

Well it's been one month that I have, I played on p120, p90, p60, P250, Korg SP200, Roland FP8,
and feel of the PC 33 seems the best at the moment (this is because it is new?)
the sounds of pianos are excellent as usual, but Rhodes is even better
as the p120 and p90.
anyway sounds are more present in the grave, giving the scale and presence. Recommended for the discerning pianists.
