When I use the kernels from Ubuntu 8.04, my MIDI latency becomes horrible. I have an external keyboard that connects to the computer and then proceeds to loop-back out to external synthesizers. By horrible, I mean that there is quite clearly a delay from when I hit a key on my keyboard to when sound comes out the synthesizer. If someone knows a tool I could use to measure the latency, I'd be glad too. Otherwise, I'd just guess it is somewhere around 100 milliseconds. When I switch back to my prior kernel from Ubuntu 7.10, the latency becomes great (but the X server and other things stop working, thanks to the magic of Ubuntu). Here are the kernels I've tried out with Ubuntu 8.10: 2.6.24-18-generic Bad latency 2.6.24-18-rt Bad latency 2.6.22-14-generic (This is the kernel from Ubuntu 7.10) Excellent latency Has anyone else had this problem? Do you know if it is kernel-related, library-related, or Ubuntu-related? It almost seems kernel-related, but why? -David _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
