CJ's blood pressure rises when he hears your using a Creative card... and for good reason too!
Sonars TTS-1 has better sounds than those on the $4 chip. You need to go to it's GUI to explore the full potential.
I tried those KX drivers in a desperate attempt to make my $300 SB Audigy card run with Guitar studio, check my posts back in 2005. The drivers that came with the card worked better than asio4all or the kx. But still a nightmare. The idea of the kx drivers was to give you access to all your output ports. Like the 5 channels of the surround system without the dolby processing.
