You can try to control what bits are dominant by doing some very radical EQ'ing between the sound board and the computer. Like using a lowpass to only provide bass tones to the visualizer. No one will be hearing your submix so it's only purpose would be to isolate the frequencies that make the visualizer look best. A programable multi-band EQ would work best here. You could set up "scenes" in this way. Also , being able to mute the input to the visualizer if some one is just talking would be a nice touch. I have played around with Gforce in this way and the results are much better than using the material unaltered.
