I am having trouble running it.

Crashes with

`Assertion failed: (pControl && "There is no control attached with this tag"), function GetControlWithTag, file /Users/cristianvogel/Desktop/Programming/iPlug2/IGraphics/IGraphics.cpp, line 423.`

Yes - there is a bug here to do with some recent changes in control tags - I had this issue earlier today - feel free to post an issue on GitHub about this and we’ll fix it. For now it will run if you build not in debug mode, or you can comment out the assert (which is harmless).
