	On many mixers you can take a direct output from each 
channel. You could take the bass, or  bass drum, or snare, or guitar, 
or vocals,  etc., and have your video controlled by which ever 
instrument you wanted.

	Better yet, if you have an unused  aux out on the mixer, you 
could sent any one or any combination of instruments to the aux out 
and then have video respond to this mix. Examples could be bass, bass 
and snare, bass drum and snare, complete drum kit, etc. This would be 
easy to control - if you wanted to emphasize a bass passage, simply 
turn down the other instruments you have in the aux mix. If you want 
to follow the hi hats just turn them up in the aux mix.

	Good luck.
