Rather than use frequency I tied the expression to the RW Opacity setting.
This is quick and dirty. You could do an if/then statement to check the min/max values to trigger the waves.

There are several methods that use expressions. Visit Dan Eberts excellent MotionScript site for examples.
I’ve put together a sample you can use. The distance between layers is controlled by the slider on the Control layer. Each follower layer has a script that references the layer above to calculate its position using valueAtTime.

You can tie one effect to another using expressions. Here is a bit of a quick demo using a slider, radio waves opacity (even if frequency is 0 an initial wave is emitted). RW and Ripple Pulse driven by the brightness of a lens flare.

Steve, I’d sure like to hear Todd weigh in on this but there was an application Adobe distributed called Adobe Clean that removed hidden items that can prevent an installation. I’m pretty sure its still available on their website.
I’d be concerned that it might screw up your current installations. Todd??

Knoll Unmult, a free plugin will help.
Place the lens flares on a black solid and then apply UnMult to drop out the blacks, no need for blending modes.
Get it free here:

The aeselflink processes are additional After Effects render engines that are spawned when multiprocessing is turned on. Assuming you have enough physical RAM to multiprocess, AND that no other applications/processes are using the RAM it works well in most circumstances.
There are 2 things that may help. First use the secret preferences to purge memory every 30 frames or so. Hold down the shift key as you select General Preferences to access the Secret prefs.
If that doesn’t do it, turn multiprocessing off for this render.

No green screen? Ouch! That sounds like a lot of painstaking roto work to me.
Is the background a static solid color?? If so, you could use several color correction techniques to push the luminance of the the actors to black and the background to white. Then you can do anything you want to the color of the actors.

Rick Gerhard had 2 tutorials on the Cow dealing with this exact technique, I’ve done a cursory search but can’t locate them.
The technique Rick uses is to tie the camera’s POI to a null with a simple pick whip expression. Animate the camera position and then the null. Its best to position the null at the camera’s intended eye level first.
Sorry I can’t find the tutorials on line.

Dave, very good tips. I’m going to try the frame rate increase.
