This is a very light portable digital piano, However the 32 note polyphony is very deceptive. As soon as you start playing the better stereo sampled sounds you drop down to 16 note. I found that the notes drop off very quickly when that happens. I found it to be absolutely terrible when you had the arranger going and you were playing the stereo samples or tried to layer two or more sounds together.
If their new series of boards actually have the 64 note polyphony that the website says then they will be much better. As for there sound...not to bad. Again the portability of this full 88 weighted key piano is what was very appealing to me. The sound level does improve from entry level models as you go up to the more expensive units. Better speakers and amplifiers I suspect.
