You're correct, except that you should attach only once 
the virmidi in read-write "rw" mode, as device 1, and then 
map 0 to 1 and 1 to 0 as you do.

BTW, it may be handy to turn on filter debug mode (with
'debug filt 1') so that all midi events are displayed on the 
console.

since i'm not a big alsa user, i'm interested on your feedback and
your tips
