Interesting! I like seeing how different people go about creating an audio rate oscilloscope in Audulus. I'm really curious to see @taylor's take on it one day ;)
@Robertsyrett - I agree! Trienas, have you seen vias in other applications? They allow you to snip off the knob and replace it with something else. It's really useful in situations like these where you have one knob or button or incoming signal getting distibuted to so many nodes.
Also, I'm really hoping you knew that you can copy/paste the node with the connection to the knob already in place and you will retain that connection, so that you didn't actually wire this knob to each delay node individually?
I got an idea by controlling three colours in each leds individually by 768 delays, 256 for red, 256 for green and 256 for blue. However it gonna take a lot of effort and enough motivation to do it.
