Please do "ls -l /dev/sequencer"

Try adjusting the mixer levels.

Do you have this line in /etc/modprobe.d/alsa-base ?:

    install snd-emu10k1 modprobe --ignore-install snd-emu10k1 && {
/lib/alsa/modprobe-post-install snd-emu10k1 ; modprobe --quiet snd-emu10k1-synth ; }

and no other lines beginning with 'install snd-emu10k1'? If not then please
upgrade your alsa-base to the latest version.

Hmm. udev problem?

You should not have to add these. Hotplug and udev should take care of
loading these modules.

It seems your blacklisting didn't prevent the ac97 driver from being loaded.

Are you able to play midi files with pmidi?
