Oh I see.
Thanks for the clarification and again please excuse my ignorance int the field of computer technology :).
Just to get it right, some of you said that I don't need a real time kernel? How that? Are there people on this list who do serious audio work and do NOT use an rt-kernel? If so is it really recomended doing so?
Thanks again to you all!
Love Linux and the community...

On Linux you don't need a real-time kernel to run real-time processes
either.
1) on linux, **access** to realtime scheduling is not necessarily
granted to normal users, unlike the situation on windows and OS X. on
any sane linux system, this is easy to alter. on any sane linux system
that targets music/pro-audio/media production, its already set up that
way and so there is no difference between these systems and windows or
OS X in this regard.
2) the PREEMPT_RT kernel is substantially "more realtime" than any
version of windows or OS X that you could lay your hands on. its more
like an actual realtime OS than the kind of general purpose OS that
regular Linux, Windows and OS X represent, though without actually
being suitable (quite) for "hard RT" tasks.
Linux machines are the standard for "high frequency trading"
Almost just because they can really go RT
