No Midi on Debian Wheezy image for BBB

Hi,

after installing some Alsa packages my usb audio card now works great on my BBB with Debian Wheezy image from armhf installed on an sd card. But when I connect a usb Midi interface my software (Supercollider) gives me this error:

ALSA lib seq_hw.c:457:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory
MIDI (ALSA): could not open ALSA sequencer: No such file or directory

I’ve found a few discussions where similar errors were mentioned and from those it seems like the snd-seq module is not present on my system. It’s missing from the kernel.

Now, my problem is I have never compiled a kernel myself. I’m not afraid to try but I just don’t have enough information yet. I have cloned this

https://github.com/RobertCNelson/stable-kernel

into my home directory. Now what? Where can I configure modules? Do I need to build the whole kernel or can I build and add specific modules?

Could someone please take me by the hand a little?

Thanks in advance,
Axel

Wrong git repo for the black...

Even thou you have a root file system installed, you can still follow
the linux build/install instructions at my wiki here;

http://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-LinuxKernel

into my home directory. Now what? Where can I configure modules? Do I need
to build the whole kernel or can I build and add specific modules?

It's probally one of the optional sound modules.. If you get it
working, please send a config patch and i'll add it by default..
