Need Help Audio Amplitude Output Controlling Multiple Parameters

Question

What I am trying to accomplish here is having one audio track effect multiple parameters, obviously all of the parameters would be slightly different so I'm not just making duplicates of one object.
Anyways, is there a way to use the audio amplitude to effect multiple parameters. I want to only have to analyze the audio one time, and then have that analyzation control multiple things. I've tried a Rig, but that doesn't seem to give me the options I need to configure this.

First of all, it doesn't "hurt" anything to have mulitple audio behaviors added to parameters. It doesn't duplicate the audio in any way. What IS the PITA, is you really have to wait for the audio behaviors to "process" (all the way to 100%) because if they're interupted, they'll often NOT finish creating the keyframes all the way to the end of the project.
You can easily add Link Behaviors to anything that is already under audio pararmeter control. You can chain them indefinitely.
However, one good example that might be coincidentally convenient is to create a Number Generator, turn off Animate and link the audio to the Value. Make sure, in the audio behavior to set the Scale value to the maximum value you will need (default is 1 and number values from 0 to 1 are not terribly useful for most things in Motion.)  You can subsequently link other parameters to the Number's Value (Object.Numbers.Value from the Source Parameter dropdown in the Link Behavior). You can use the Value offset and Scale parameters in the link behavior to "shape" the behavior for each subsequent parameter under control. The sometimes useful side effect is that you have a visual number to monitor (you can set its opacity to 0 to hide it for the final project appearance.)
For the image below, I created two Number generators and linked the same audio file to each, setting the left number value to the Left Channel of the audio and the right number value to the Right Channel of the audio. I created a small rectangle and created two Replicators off of it (Shape: Rectangle/Tile Fill/Columns 1/Rows 15/ Origin Bottlom). I used Color Over Pattern to color the "audio meter" effect and a Sequence Replicator with an Opacity parameter, Sequencing To, Traversal Custom and to the Location parameter, I linked each back to the corresponding Number Value (Scaled to 100 for percent in the Audio behaviors). The Link behavior to each Location has the Value Offset set to -100 [location works from -100% to 0%].
You could link any number of parameters to the Number Values, and not have the audio parameters re-analyze all the time.
