Hm..."oops". Actually, it works for me as well, but the error messages were so
intimidating that I didn't even dare to test whether it actually works :-).
Seems then that the wrong MIDI channel in QSampler was my only problem.

So, yes, I can now create 2, 3, 4 tracks in Qtractor and corresponding channels
in QSampler, all loaded with different .sfz instrument files, and it works just
fine, as expected. Thanks, this makes me a good deal happier! :-)

Of course, the next natural question is then why we see those really
irritating error messages - are Qtractor/Qsampler and LinuxSampler not speaking
the same protocol/version? I mean, this is "as unintuitive as it can get"; please
don't say now "works as expected", ok? :-)

Greetings,
Frank
