Not an owner ... but I've read most of what is out there concerning the ETC.
The visualizations are based on either a oscilloscope type function or a trigger type function. The scope modes will continuously display a visual representation of whatever audio you feed it. If you feed it your whole mix, it will be very active/busy. If you feed it a solid square wave, it won't move at all. Maybe try feeding it just the hi hat or bass? The trigger modes are designed to "animate" (for lack of a better word) when your audio crosses a certain threshold. Once again ... if you feed it your whole mix, it will be very busy looking. Feed it a simple or sparsely active signal and it will calm down.
Like you, I'm not interested in rapidly flashing visuals. I plan to code my own based on sprites ... but my questions to C&G have gone unanswered.
Anyone out there coding with sprites/spritesheets?
