Hi Tony

When I say "whatever style changed" it's the same band playing, I mean that
it's a big difference between Ketron and other brands in this case as long
as you use the internal (or factorysupplied) styles.
At the SD1 you can swap from one to another without a lot of tweaking and
still it sounds like the "very same live band performing at the stage".
The sounds/voices are well balanced, and I feel the different instruments
are sounding much better now than the first time I heard and tryed it out
some years ago.

Of course there are different sounds and instruments used when change between
all the styles, but the overall way SD1 sounds don't make me "jump high in the
chair" and give me the feeling of that it's another CD playing when start play
the next song.
The brand nearest to SD1 when give a "live" feeling like this, I think most
be Korg.

Hope what I try to describe is understandable.

Cheers
