you probably need to 'sudo modprobe snd-seq'.

if you can get it to run, you should be able to record the midi stream
from aubionotes in jack mode using a sequencer. but beware, aubionotes
is quite broken at the moment, i.e. very greedy and unstable. 

most of its problems comes from the midi threading. i will make sure i
also think about writing to midi files when i have the time to fix it.
this would also be useful for the other command line tools.

cheers, piem
