Perhaps you can leave the individual outputs at their respective 
levels and attenuate them separately for the sum mix output.

I think this module should be designed to have the reset and gate 
functions implemented to make it more creative than simple ad eg's 
and lfo's. I think these features alone will add more creative charm 
and function to the module.
