It seems strange that snd_seq_midi is missing on ubuntustudio 12.04. I've seen
a post where it's missing on the remix version of 12.04 though.

Try:
modinfo snd_seq_midi
This should show if it actually does exist or not. If it does, according to
some docs on jackd it may need to be forced at bootup. Worth a try, so add
snd_seq_midi on one line in /etc/modules then reboot and check lsmod again.
