Until I retired my Win98SE system recently I was using the kx drivers with its Creative Platinum card, and although it worked ok I could never begin to understand the driver's control panel and features. The most simple thing seemed to require endless fiddling with several badly designed interface pages.
While I agree with your assessment of the kx driver's usability, I would point out that since these are consumer cards, the native Creative driver / mixer / software package was so cutesy that I found it even more incomprehensible. While I still have that Creative card on one PC, needless to say for my serious audio machines I now use more appropriate gear.
Does anyone has some experiencing with this driver? I'd like to know some opinions about it.
Well, you are aware that we are not too fond of the Creative cards so you may know this, but I'd just like to emphasise that using the kx drivers won't change the fundamental problem (for many of us) with the cards, and that is that they only really operate at a sample rate of 48kHz. In fact, I think the kx ASIO drivers only offer 48kHz, so you can't get this wrong. But, be aware, that's what you are going to have to work with.
