I also have an Edirol UM-3EX USB 3-port Midi interface that's being

one of the things I'm murky about, and hesitant to screw with).
As a 32-bit two's-complement negative integer, -2 in binary is
11111111111111111111111111111110. This means that the snd-usb-audio
driver is allowed to attach to any index except 0. (If the USB driver
is loaded before the HDSP driver, you lose.)
If I enable the snd-virmidi driver, I'd like it to be even lower in
priority than the Edirol UM-3EX Midi, and be last.
Do not use the index= option. Always use the slots= options of the snd
module instead.
options snd-... index=...
...
# options snd slots=snd-hda-intel,snd-hdsp,snd-usb-audio
Remove the index= lines, uncomment the last line, and add the
snd-virmidi driver where desired.
Thank you very much for explaining that... It looks like I must have
been looking into that at some point, but commented it out instead of
trying it. It's certainly looks a lot easier with slots=.
