Hi, I am really new to fmod and not super great at c++ either, but I have experience with audio programming in JUCE and other stuff. I understand that I can use one of the example plugins like fmod\_gain from the api/core/examples/plugins as boilerplate for writing a custom plugin. In order to use them in fmod studio, I see you have to compile the cpp to a dll file to then place in a the plugins folder. Before I jump into any custom dsp stuff, I’m wondering how I should build the example cpps into dlls. The reference pages quickly gloss over this compiling, but maybe I overlooked something.  
Any help on this would be awesome! 😃  
Thanks

Hi,

The `.dll` can be build from Visual Studio via the context menu:

Then the `.dll` can be put in the plugin dir:

Hope this helps!

Perfect, thank you so much !! Sorry, never used visual studio before, I see now it’s a really simple process. Thanks :3
