@d-healey I did compile it from source (my first time compiing anything as well) and it was the develop branch. Maybe I'll compile it once more just in case I did something wrong.

Thanks for your help, David! I can't believe how fast you responded. I hope to have more meaty questions in the future.

@d-healey Yes. I think I was wrongly assuming I had to "Save XML", but that's not working for me. "Save archive" is working. Is that the preferred way to save any changes?

I just compiled my first try at a VST plugin. I can't believe it! It's not working yet (I need to figure out how to embed images and wavs, I'm sure there's plenty of info in the forum about it), but I'm getting there! This is great.

When I try to "Save XML" I get this message. I don't know how to fix it.

Also, I'm not sure if this is the proper way to save any progress.
