bad midi timing

Yes I do understand. Your sequencers really have no timing and ...

Do you run 64studio as the user of the installation? If not please check
the groups by running 'id' in a terminal. But if you can use audio
duplex without getting problems groups and /etc/security/limits.conf
maybe ok. Hm, cpu-usage under 10%, however please run 'top' in a
terminal and post it.
Have you checked your RAM, hd-drive etc. with a memtest and programs
Have you run jack and applications like roesegarden as root? If not
please try this to see if there is something different.
If your audiocard is able to produce PCM music I don't understand why
MIDI won't work. I've installed 64studio 2.1rc1 some days ago and I just
tested the quality of the sound and to connect to all needed MIDI ports
but not if the MIDI timing is correct. I won't test it today but I don't
believe that I have this problem too.
Can you manipulate the timing fluctuation by moving the mouse, open
pictures or something else? If you run 'jackd -R -d alsa' or qjackctl
there are no strange messages displayed?
Also non real time kernels do real time but not very well. The menu.lst
is ok? Have you controlled if you are booting the right kernel by
running 'uname -r' in a terminal? The installation medium also is ok?
Maybe you can verify the MD5 checksum.
