I think the problem has his cause somewhere else??!
I have no daubt that Mixvibes maybe work correct at polocorps PC (and maybe the other 100 turntablists at the forum

)
But it´s a fact that mygo and me got problems to run Mixvibes in the right way.
There are 3 (in words three) possibilties why mixvibes don´t work correctly at my PC.
1) The Hardware
I Use the newest hardware, a very good soundcard, good needles/turntables...... So that could be not the problem.
2) The User
I used Mixvibes for 4 years now. And hand on the heart: Mixvibes ain´t got so much configurations that you could make something really wrong!?
3) The Software
????
Can´t say nothing bout. Only Thing i know is that i got with 6.411 and v2 records no drift. Since Version 7 it drifts. (to be honest i have not tested final version because right now i´m so happy with my new setup).
btw. it has not only drift in rel. mode.....it has drift also in absolute mode. It was annoying which had me let buy another DV-System.
So, it´s not my job to find out what causes this problem. i can only tell what´s happening.
