The “Mixer” project is a really good demonstration of the Pretty Good Jacktrip Toolkit. It can be used as an appliance — set one up, bring folks on board and go. But it’s also a good demonstration of how the PGJTT can be used to learn or build new things.
This video is a tour of how it all works, but it’s not a comprehensive tour of how the Ardour DAW works — you will definitely want to have a look at the Ardour Beginner’s Tutorial and the Ardour Manual.
I tend to ramble, so this video has some bumpy bits where I chopped out stuff. 🙂
