Looking at the demo songs, I've noticed that some tracks have more than the usual 5 channels, some for example have a Saw channel.
How can I get them into my project?
Expansion audio is selected in the project properties. VRC6 is the one that had a saw channel.
You should take some time to watch the 1h tutorial. Best of luck.
