I think I played straight into Logic with the metronome on, two sections and then pushed that forward to create some blank bars for the intro and then added the drummer on multiple tracks and same for bassist, then fiddled with some of the settings for each section.

I was pretty impressed, though, for approximately ten minutes start to finish. I should probably go recall what I played so I can try and finish the riffs off or something.

An actual competent musician ought to be able to make the most ridiculous demos with this thing.
