**VCI-400 Latency Problem** Hi, I´ve bought a VCI-400, installed erverything and so on. Now, when I use the build-in-soundcard (with Traktor Pro2) of the VCI-400, I´ve latencys of 85ms! If I try to bring the latency down, i get crackling sounds and the the audio stops. When I´m using my old external soundcard instead, I´ve got latencys of 15,1ms. So whats wrong. I paid 800€, so I want to work with the build in soundcard (+ if I use the external soundcard, the headphone-out of the VCI became useless). Please help!!! ---

The VCI 400 is quite new, so I doubt many people can help you. What kind of computer do you have? Usually latency issues are caused by a mixture of hardware and software details, like a slow computer and bad drivers. So, since the VCI is new, it might be a driver issue, but it could also be you have a computer, that doesn’t have the power needed to run the VCI with Traktor. For instance, interesting is, the VCI doesn’t support celerons, Atom or AMD processors. From the Vestax website.

> [@scamo](#): > > For instance, interesting is, the VCI doesn’t support celerons, Atom or AMD processors. It is kind of interesting, but they even said that about the VCI-100 which was MIDI only. What I think this actually means is that they save a bit of money in testing, and only test with Intel CPU/chipset combos. There’s a specific mention of some Sony Vaio laptops though, I hear the problem there is a USB conflict with the built-in webcam.
