Hmmmm....
I think we can compare the different taste regarding sound streaming into
our ears as we have different opinion when we smell or taste food.

No matter who or how played, we'll experience this in a very personal way.
Either we like what we hear, or we don't.
Lucky us that we can adjust a lot by use of EQ and effects and choose between
different PA equipment to make it sund just as we like.

I find this topic similiar as when discuss religion. We can carry on discuss
it forever, but we should agree on that we won't nessesary have to come to
any common conclusion about whats the right or wrong.
Guess that's why we witness countless conflicts and wars, never ending story....

All that said, I agree that the factory demos should mirror the keyboards as
it is out of the box, and then maybe make a more in depth demo where some of
the possibilites and settings for personal satisfaction could be displyed.

Happy Playing & Listening
