I was just trying to do the same. I got curious about JUCE just recently and I’ve been fooling around with it for two weeks for now as a side project, but it is a bit hard to grasp how to combine these two examples, so I’d very much appreciate any code that I could have a look at how to implement such a feature.
If you aren’t too shy about sharing your code, no matter how crude, it would really give me a good kickstart here!
