Have you tried playing with dd? `dd if=/dev/midi00 bs=1 of=patchfile'
might do the trick. Mmm..advanced sound apps. :9

I've seen repeated statments that esd is real-time hostile. I don't
know if this is true. I like the *general* concept and I think it
could be made real-time and network friendly.
