I'm a complete newbie on these matters, so I might be completely wrong, 
but I thought that sample rates were relevant to audio files, but not to 
MIDI files? Well, I think the problem is not even related to the MIDI 
file: If I just play A in the Virtual Keyboard, it does not play a 440Hz 
A, it is somewhere around C.

Any ideas where to look for what could be wrong with my software/computer?

Thanks,
