I have a hard time finding easy to understand literature or video tutorials that help me with achieving my goal. I have attached a photo of my project in my post. I created a quick sculpture by drawing over a photo. There is a outer tube and a inner tube. The inner tube contains a standard illumination texture.
I want to find a way in which the illumination within the texture automatically responds/is affected by a music track. How do I achieve this? I have only seen tutorials in which a visual audio bar/ is created, such as GreyScaleGorilla or eyedesyn and it is not related to what I want. I want to be able to create something that automatically flickers on the music, or changes the colors based on the heat of the music. I have not been able to get anything to work with the sound mograph in C4D. I am running C4D R21
Many thanks in advance guys!!

I think one approach is to have a cloner with two ‘states’ inside, on and off. Set cloner to sort, set sound effector to modify clone, then the sound will switch the clones between the states. I think this will give a stepped change so either 100% on or off, another approach would be needed if dimming was Required. possibly some re-mapping with xpresso.

I made a little test using xpresso, a plain effector that uses sound effector field to effect clones scale… Then I take that data out and pipe it into the luminance channel. Now, I’m no xpresso wiz so it could be wrong or there’s a better way, but this I think gets you what you want. Then just duplicate the set up per material you want and move the probes in the effector.

Here’s another xpresso option that’s a little simpler. Take a look at this older tutorial on using a sound effector with a displacer and then substitute whatever parameter you like (I used color brightness in my example below) in place of the displacer.Some contents or functionalities here are not available due to your cookie preferences!
As I did in my example, you will need to add a solid layer in the sound effector’s falloff as C4D’s handling of it in xpresso apparently changed after R19. (see this brief discussion on the issue – https://www.c4dcafe.com/ipb/forums/topic/109300-sound-effector-output-to-drive-animation-with-xpresso/)
You may need to load your own sound file into the sound effector in my example.

I forgot to mention in my previous post that in order to access a material’s parameters drag its icon from the attributes window, and not from the object menu, into the xpresso window. You will then be able to click on the corners of its node and have access to all of the material’s parameters.

Hi Jim and Andy
Thank you so much for your help! I think both your input will help tremendously in solving the problem!
