I'm using Lorenz as a modulation source, but it
appears that amplitude
decreases greatly as I slow down the rate. Is there a high pass / DC
blocking filter somewhere in there?
Yes, there is.
This effect of the hp filter will be greatly reduced when I get to
implement the same fix that the Roessler fractal has already seen,
subtraction of a DC constant on each of the three axes.
Thank you for the reminder,
Tim
