-Since Debian Wheezy an RT variant is also available in the [[https://packages.debian.org/search?suite=default&section=all&arch=any&searchon=names&keywords=linux-image-rt|stock repositories]]; unfortunately its system timer is set to 250 Hz instead of 1000 Hz, so you'll probably want to recompile your own kernel anyway, especially if you use ALSA MIDI. These kernels incorporate [[http://pengutronix.de/software/linux-rt/debian_en.html|Pengutronix]] patches (see [[https://wiki.debian.org/DebianMultimedia#Realtime_kernel|DebianMultimedia Wiki]]). The [[http://www.64studio.com/|64 Studio]] real-time kernels are in the backports apt repository, so for Debian Squeeze you will have to add the following line to your apt sources list: +Since Debian Wheezy an RT variant is also available in the [[https://packages.debian.org/search?suite=default&section=all&arch=any&searchon=names&keywords=linux-image-rt|stock repositories]]; unfortunately its system timer is set to 250 Hz instead of 1000 Hz, so you'll probably want to recompile your own kernel anyway, especially if you use ALSA MIDI.
