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 : [ 20.269196] Adding 530136k swap on /dev/sda3. Priority:-1 extents:1 across:530136k [ 445.142031] snd-usb-caiaq log: snd_usb_caiaq_midi_send(ffff81007f9380c0): usb_submit_urb() failed, -22 [ 445.393030] snd-usb-caiaq log: snd_usb_caiaq_midi_send(ffff81007f9380c0): usb_submit_urb() failed, -22 [ 445.640986] snd-usb-caiaq log: snd_usb_caiaq_midi_send(ffff81007f9380c0): usb_submit_urb() failed, -22 [ 445.892008] snd-usb-caiaq log: snd_usb_caiaq_midi_send(ffff81007f9380c0): usb_submit_urb() failed, -22 [ 446.141982] snd-usb-caiaq log: snd_usb_caiaq_midi_send(ffff81007f9380c0): usb_submit_urb() failed, -22 [ 446.392962] snd-usb-caiaq log: snd_usb_caiaq_midi_send(ffff81007f9380c0): usb_submit_urb() failed, -22 [ 446.640967] snd-usb-caiaq log: snd_usb_caiaq_midi_send(ffff81007f9380c0): usb_submit_urb() failed, -22 [ 446.891986] snd-usb-caiaq log: snd_usb_caiaq_midi_send(ffff81007f9380c0): usb_submit_urb() failed, -22 [ 461.651199] CPU0: Temperature/speed normal 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 ?
