Where are the C8 Sample Projects?

No… you do exactly what I described and go into the Rock Pop Toolbox.
and you’ll find the PROJECTS folder there with the content.

Not just loops and samples!

There’s 29 individual Allen Morgan example projects there.

On Windows…
C:\ProgramData\Steinberg\Content\VST Sound

But the files are packed in what is probably an NTFS File Stream so you need to use Mediabay to get at them.
