On second thought... We've been here before. From my Linux MIDI Guide:
Note: There are variations on PREEMPT that are less than ideal.
"DYNAMIC_PREEMPT" allows PREEMPT to be turned on and off in the kernel
command line options (preempt=full). You'll need to check your GRUB
We rely completely on ALSA for timer stuff. The key routine for
setting the timer in RG is:
AlsaDriver::setCurrentTimer()
Unless there is a bug in there (which there may very well be, the
ALSA documentation is incomplete and in many cases incorrect), the
problems tend to be due to bugs
Hello,

Do you happen to remember off hand which parts are incorrect? I think we
should report them to the ALSA project.

Will, can you go through this first draft series of steps on the
problematic box and let me know if it finds the issue? Thanks.
Boot into the problematic kernel.
Confirm that it is a preemptible kernel.
$ grep -i config_preempt= /boot/config-$(uname -r)
CONFIG_PREEMPT=y
If you
Well, I've made a couple of attempts to use Ardour. It's a very powerful
tool of audio engineers.
For someone more ordinary, like me, who doesn't do much with recorded
audio, it's way beyond me.
Rosegarden does the MIDI and scoring I need. For a final, complete,
beautiful score, I use
I haven't noticed any problems but the current standard kernel in
Fedora 36 has:
CONFIG_PREEMPT_DYNAMIC=y
CONFIG_PREEMPT_VOLUNTARY=y
in /boot/config-$(uname -r)
does this need to be overridden in /etc/default/grub or in a kernel
rebuild ?

Will,
Not to steal a thread, but rather than rosegarden supporting all these formats, have you considered rosegarden becoming a plugin so that you can use it in say, ardour. Keep rosegarden a special notation piece, and let others worry about the extra fluff.Sorry if this has been considered
