Hi Tim,

So it must be the configuration on my part... I thought so.
Ok; I'll try that, too.
I diasbled not-used hardware in the BIOS, not-used services, and I start
the laptop without the PCMCIA WLAN card. Still... hmmm maybe I should
blacklist everything except PCI/USB? Or even turn off hotplug and try to
configure the USB port myself?
It gives me lags with just one piano track, or with Rosegarden's
metronome alone...

Hmmm ok - but 'apt-cache search aadebug' shows me nothing here... have
to google for that later (when back home).

Oh oh - sorry I didn't do that until now. Ok: [my hard &
soft]
Very similar to the system I'm running. I only get MIDI timing problems when I
max out my CPU (more than a dozen simultaneous parts in Rosegarden). Have you read all of this:

http://demudi.agnula.org/wiki/DocumentsTips
yup; btdt - but without much success. What gives me headaches is that
the standard DeMuDi Live-CD or a clean install of it give me the same
lags as with my 'Sarge' with additional kernel/packages from the Agnula
repos...
No .asoundrc
(maybe that is the cause?); jackd is started with -R -d
alsa or with jackstart from qjackctl.
It's worth making a ~/.asoundrc - I doubt whether that's the cause though.
It helps a wee
bit if I use Fluxbox instead of Gnome, as does using Muse
instead of Rosegarden.
Yep, it can also be worth disabling some services.
http://demudi.agnula.org/wiki/DocumentsFaq#XrunsOverruns The lags and
timeouts (xruns) start being worse when the screen starts
scrolling in Rosegarden/Muse.
For complex pieces it can be worth turning off the playback follow option and
various other bits of eye-candy in Rosegarden. It should run smooth for a
four-part arrangement on your system. Hmm, maybe worth disabling acpi in the BIOS? I
don't really understand how USB
works. Which bit of hardware uses it? the keyboard?
BTDT. No success. And the USB ports on that particular ASUS laptop are
used for a Logitech mouse (because I hate these touchpads) and the
MidiSport 2x2 interface to get in my MIDI events and to get them out to
the Sound Canvas again, which actually plays the whole stuff.
