Hi Takashi,
I have almost the same problem as Marco. (that is why Marco forwarded me
this message).
Well, Now it seems to be almost perfect. Just to explain to you :
I had a problem with Pure data, each time I wanted to enable the alsa midi
(in pure data). Then I had some problem opening some of my patch, making pd
zombified and Jack output tons of "delay of 1666.000 usecs exceeds estimated
spare time of 1140.000; restart ..." until I stop it and run it again.
Now pd works perfectly. I made some others jackd settings, and the "xruns"
messages seems to gone away.
But like Marco I got this message in the output of dmesg :

infos :
kernel : 2.6.26.8-rt12 (with the last patch solving alsa midi problems).
OS : Gentoo 64bits.
Sounds card : NI Audio Kontrol 1
alsa : 1.0.16 (with your patchs now.)
Thank you for your help and your great job. I can use pd now, my main
software to make music. So I am very happy :)
Just a thing, when I press the buttons on the top of the Audio Kontrol 1 I
got qbc (azerty keyboard). but When I move the jog, the system log out.
Did anyone find a way to change the assignation of these buttons ?
Kind regards,
Mysth-R
