A tutorial is needed to show AudioProcessorGraph usage in simple and concise application.
As nice as the Audio Plugin Host demo application is (I use it every day for quick testing), it is not a particularly good example of AudioProcessorGraph usage because the relevant code is scattered all through multiple source files. Plus, the graphics UI is not needed for many applications, and so it ends up obfuscating the areas of interest.
So, a nice simple audio app, showing how to connect the audio hardware, add a plugin (from a list), and play something, would be very helpful to those new to JUCE.
I’m past most of those struggles myself, but the knowledge was hard won by reading many, many posts in this forum, and anywhere else I could find discussions or mention of AudioProcessorGraph.
A new tutorial would save others from the pain.
