Hi, thanks for all repplies...
We were barking the wrong tree!

It was BROKEN, and I sent it to the vendor. Then, bought 2 EWIs (ouch!!!, first I've bought the new,unused 4000S, then appeared an used, like new, cheap EWI USB, not possible to resist), that is, boght an used EWI USB and a new EWI 4000S. Both work fine, as expected, easy...
Now, problem is ME...

The factory sounds from the EWI 4000S (internal synth) are poor (very poor in my oppinion).
The sounds from the ARIA AKAI softsinth (for the EWI USB) is only fair, but is possible to load new samples...

It is possible to buy a replacement set for the EWI4000S internal sounds (from Patchman), about US$ 100,00, but will not buy without try them...
Maybe I´ll try a Ketron SD2, but it is very expensive here in Brazil.
I would prefer that EWI4000S internal sounds were good enough.
And, after all, the main problem is still ME!
