I use the following in  -+rtmidi=alsa -Mhw:1,0 

but before launching csound I have to create raw midi ports with the commands 
(without these no way to have midi work):

modprobe snd-virmidi 
aconnect 130:0 20:0

(take a look at jackd connections to understand what you have to connect) and 
everything works.
