Diki, when I installed the drivers, it loaded[defaulted?) to 5 ms..It works perfect ..no crackling, distortion of any sort...I did not try to lower the latency more[didn't need to}, but I will experiment and see how low I can go...
I am using XP Professional, and a Pentium 4 on both my laptop and PC..

My other drivers get down to about 13 ms {before static)...I can tell the Edirol drivers are superior..
