Very strange, I just send this mail to the list Will, there seems to be something wrong for the mail I send before.

I'll reboot into memtest86+.bin now. I guess there will be no errors for
the next 10 or more hours. But who knows?

I never got troubles when doing this. I have to check it again.

I also never got troubles for that. I also will check this again.

The same thing, in the past no troubles with that. I'll check this again
too.

When Rosegarden is playing MIDI events and recording them as audio
track, I also never got problems, but I guess while playing a loop to
adjust the recording level, there was trouble, but I'm not sure.

This caused Rosegarden (can't say if it's like that for 1.7.1) often to
crash, but not Zyn, but QSampler did crash, while Rosegarden doesn't.
I'll test everything again, because I didn't made those tests with 64
Studio default. Suse's Rosegarden 1.6.1 crashes like 1.7.0 for 64 Studio
and Suse does.

Instead of QSynth I'm using the Fluidsynth DSSI plugin, that seems to be
stable, QSampler seems to be buggy and Rosegarden and maybe jackd could
be buggy too.
Have a good night,
