The old /dev/sequencer stuff died with ISA bus midi synths. None of the PCI sound drivers support it.

demolinux: was not properly detected knoppix : ok Module trident.o was detected on boot with the redhat scripts (kudzu).
Sound works with trident.o from kernel or the ali5451-driver from alsa. The alsa driver should be better. Maybe midi works with alsa
Alsa driver on kernel 2.6 : 'snd-ali5451.o'
# modprobe -v snd-trident insmod /lib/modules/2.6.0-test4/kernel/sound/pci/trident/snd-trident.ko
But you can hear the Interruptions through the headphone. It seem that the mixer is shuffled : master is assigned as 'pcm1' and 'pcm1' mapped to 'pcm2'.
MIDI is supported on windows, but I don't know how to on linux.
