On timing...

Maybe I am out of the track but...

Using A PII 350 whith an (superMPU64) usb interface.

I had similar problems with timing and, in my case, the problem seems to be the folling

I have a virus sheeld (norton) and after long and hard tests, I came to the conclusion that the antivirus slowes (ALL) operations on my computer.

I desactivate, it when I am in music session. Curiously, I did'nt have any timing problems since!!!
