At last the final solution for all relating to Native Instuments unreliable drivers for those using Traktor S4 with Windows. I have had the Traktor S4 since it was released the laptop i was using fell well within the perameters required to run Traktor S4, but when i installed the S4 software and subsequently the S4, there were drop outs and freezing. After reading all of the posts available i reluctantly bought another laptop, it was unnecessary as i was about to find out for the first time last night.The new laptop performed not too badly but when you put the S4 through it's paces or asked it to do erratic things it would drop out for a second or so here and there , enough to drive you out of your mind. I asked it to do extreme things to try and make it crash. I succeeded and it was then that i decided to plug my Maya 44 USB sound card in and load the drivers . I selected it under the Audio section on the Traktor S4 control panel thus doing away with the S4 s own soundcard and drivers . Hey presto it was as solid a a rock with no glitches even under extremities. I have tried it with all of the Windows systems from XP onwards and it has the same effect with all rock solid . I even tried it on my old laptop , same results , fantastic i am extatic. This will more than do until Native Instruments get their driver sorted out.
