This is probably the same problem I'm working through at the moment.
I think it has to do with udev not having the proper scripts to set up the
midi sequencer. /dev/snd/seq (or some such name). 
If you run "mknod -m 666 > /dev/snd/seq c 116 1". The midi things work
fine. However I've looked around for the rc.local file to run this script
at startup but ubuntu does not appear to have one.
Is this right? Can we just create one and would it work?
