I've been struggling for a few months now trying to get Vuo to control addressable LEDs (neopixels / ws2812bs) over serial.

The part that I am failing to understand is how to package up a list of RGB pixel values in vuo and send them to a serial device (such as Arduino or Teensy). I've been experimenting with some Arduino sketches specifically for this such as: https://gist.github.com/Yona-Appletree/6490993

Very nice @Magneson. Not totally clear on how you are generating those movie tests, are those in Vuo? Or is it Oscilloscope music software (not seeing which one it is on http://oscilloscopemusic.com/software.php ?)

As for shaders, it sounds like you're referring to coding a custom shader for vuo? Probably beyond our capabilities at the moment but sometimes we are fortunate to have talented programmer volunteers working with us. What are the main tips/resources we can look at to get programmers started in the right direction; Vuo SDK?

Nice contributions @Magneson. A virtual Cymascope is definitely on our to-do list! What are you referring to by a using a shader?

Have been making good progress with manipulating nodes of a 3D sphere via scaling (as you empathized) and will share results soon, however modeling sound wave phenomena would definitely be the holy grail for digital cymatics!

Answer: Use Soundflower to create an audio output device in the originating software and Soundflower will show up as an Audio Input in the Receive Live Audio node.
