    Hi everyone,

    Some users have reported audio issues under Windows with the interface integrated in Kontrol S4. Our tech support has evaluated these reports extensively, and has come to the conclusion that on the affected computers, the operating system was typically not properly configured for best audio performance in the first place.

    This means that these issues can typically be fixed through some general OS configuration and tuning measures. If you want to optimize the audio performance of our Kontrol S4 under Windows, please consult the following knowledge base articles:

    Windows 7: http://www.native-instruments.com/knowledge/questions/847

    Windows Vista: http://www.native-instruments.com/knowledge/questions/354

    Windows XP: http://www.native-instruments.com/knowledge/questions/343

    Some additional technical background: The audio drivers released with Kontrol S4 have a fixed, small USB buffer setting, while the previous NI driver generation had an adjustable USB buffer. We have found out that this small default USB buffer setting, while ideal for most computers, can be challenging for maschines that give inferior audio performance due to their general OS configuration. This is why on these computers, the S4 audio performance might appear inferior compared to an Audio 2/4/8 interface with the previous driver generation (and larger USB buffer). We are also testing a new driver version right now that will make the USB buffer adjustable again.

    Regards, Thomas
