A more basic question... what parameters are you using when you start
jackd?

-- Fernando
  
      
.jackdrc:

/usr/bin/jackd -R -P70 -t1000 -u -dalsa -r44100 -p64 -n2 -D -Chw:0,1 
-Phw:0,0 -S -i2 -o2

    

USB-Devices often perform much better with -n3. Furthermore I would try
to eliminate any flag, that is not absolutely needed such as:

/usr/bin/jackd -R -dhw:1 -dalsa -r44100 -p64 -n3

BTW: this would compute to around 4 ms latency - is that good enough for
you?

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.
