You can look at JUCE’s MIDI demo (viewable in the DemoRunner):

Thank you, thank you! This appears to be exactly what I was looking for. 😀

Also, thanks for mentioning DemoRunner. I had not come across any reference to that yet, but now I’ve found it (JUCE/examples/DemoRunner) and this will be extremely helpful.
