Eugene told me: "You need to take a Windows PC, load DSP effects such as “Surrounder +”, then make a ‘snapshot’ of the DSP configuration using kxctrl, and later attempt to restore this snapshot on your Mac." I used a PC with Windows 10, plugged in my Audigy Rx and installed the Kxdrv3553 driver. Where can I found the DSP effect "Surrender +" to download? And how can I install it? Should I need to use the kX DSP applet form the xK Mixer? Please help me.
