Are we talking weeks, months, years, or > "forget about it"? Apparently a new rt kernel patch tree (a git repository) is being created. Apparently we could see a new rt patch in the 2.6.28 timeframe... (no hope for 2.6.26/2.6.27, apparently) I posted a while back about the midi problems in lkml but there was not that much feedback. One suggestion led to a working midi input for external interfaces but the internal timer seemed to still not work (and I was not able to follow up). And I have no idea about the core reason for the problem.... BTW, Ingo is not the only rt patch developer... -- Fernando _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
