Here I go again, but running this sample doesn’t seem to match up to what I am learning here. I am by no means a spring chicken dev but I thought I would mess with plugins as I study DSP. As you can see in the screenshot, there are no pins on the Plugin at all but in the PIP, we declare all MIDI in/out and effect. Can anybody point me out to the obvious? 🙂 ![arp-1](https://us1.discourse-cdn.com/flex026/uploads/juce/original/2X/a/aac9a047454c0ca1f71e9dfaa447d186203dbfc5.png) ---

Isn’t there some constructor thing that’s supposed to happen that sets up the audio in/out and a ProJucer setting that sets up whether or not the plugin accepts MIDI? ---

I’ve run into the same obstacle, feel like I’m missing something obvious but can’t figure out what it is. Did you find a solution to this? ---

Honestly I can’t remember, this was when I was fooling around with the tutorials, so I may have figured it out but it seems like this is one of those gotchas if you slightly misunderstand a setup configuration. ---

Fair enough, thanks! I’ll keep muddling through, I’m sure it’s something fairly obvious ---

Did you enable these two options in Plugin Characteristics? ![image](https://us1.discourse-cdn.com/flex026/uploads/juce/original/2X/4/4f871a770bbe8f2a089844c49111543cfe20da31.jpeg) ---
