Roel,Bob and Dnj, Thank's for your replies

As said here, the manuals have to be very good as long as the user interface
is so "bad" as it is on the SD1. But I asume it is a matter of learning
how too do this and that.
That's remains me about Alec Pagida's excellent new "add on manual" for the
KN's. Someone should have done something similiar for the Ketron's too.
If I don't remember it wrong, the Norwegian importer is going to make a
special manual for this country, so it maybe something more coming to add to
the original one.
I agree in the meaning about the native styles in SD, this is rhythms who
fits very good to Nordic/European users.
Also SD1 plays very "live", and it's no problem to "reach the goal" when
gigging Saturday nights only by use of the internal styles.(At least for a while)
Technics have really good styles onboard too, but more the USA and Alps/Tyroler
way, with too much BigBand and "Ompa-Ompa & Jodel" for my taste.
But that's not any problem, if you remember the excellent composer you'll find
in the KN's, and who is so very easy to use.

Regarding the sounds, the warmth sounding tone is something both Ketron and
Technics have in common in my opinion, i.e. Yamaha sounds much "harder".
But that's my ears, others may hear it totally different.
And yes, my dealer is very competent and serviceminded, and I'll get all the
help and service I'll ever need, that's not any problem at all.
It's just that I was trying to find out something by myself, and it's the first
time that I've struggled so hard with finding out elementary things.
The "freeze" issue is something that amazed me a bit, because I thought this was
history nowadays, at least when only changing rhythms during play.
And I agree, it's not acceptable during a performance.
But now it is too much focus at the bad things, I'll try to find some more good
things during the weekend, if I only can figure out how to do things......
