From the ALSA wiki
After modprobe of the snd-ens1371 with no parameters, I got the Creative Es1371 working nice with my midi setup here. To test this i used:
dd if=/dev/snd/midiC0D0 bs=1 of=/dev/snd/midiC0D0
It also worked with hydrogen (midi in) and my synthesizer (midi out) together quite good. No errors so far.
