The weight of the 4000s is really a non-factor. A lot of the real axes are heavier. I like the idea of being able to connect directly to an amp to play. I started out with the USB model and for me the 4000s is way more advantageous. Later, Ray




I am sure you are correct in your opinion and certainly correct that many musical instruments may be heavier. However, clarinets, flutes, oboes are pretty light, but of course Tenor Saxes, Tubas are not so light.

Keep in mind that for children (at least those whose fingers are long enough to work these keys) and those who are handicapped may prefer a lighter instrument.
