ubuntu midi (jack and qjackctl)..problem with /dev/snd/seq

[David Foster]

I followed your directions on Hoary/amd64 with sblive(snd_emu10k1) and 
qjackctl errored with the same message. Using you modprobe line helped
but it still  dies when I hit the start button. I think you could put
'snd-seq-midi-emul' in the /etc/modules file and it would cure the
boot up problem.
