Okay, i had forgot to turn off the system "bips" and esd (it reduced the
number of xruns)
And yep with -n3 i 've got even less xruns and it seems they're not
audible.
I don't know if the latency is low enough though, i'll test this evening
with my drum pads.

Thanks everyone , it's really great to get so much help so quickly.
