hello, the lowest latency i could get is with the CCRMA low latency 
kernel patch.
On a cheap internal audio card and an USB midi sport 2*2,
connecting midi in to midi out gives me a latency measure on [timer] 
between 15 and 25 ms with the lowest affordable buffers (about 5ms) as 
far as I remember.
I couldn't make some other tests actually,
and hope it gives some clues...
Best,
Patco.
