With the track selected, when you speak into the mic, do you see a signal bar moving up and down on the right-side of the track? If not, then your mic is not assigned to that track, or your audio interface isn't configured correctly in S1. What you got with Studiolive 32 wasn't a demo version of Artist, but the real deal. They give you the $99 program for free with a lot of their hardware.
The first thing I would look at is the Audio Setup in Studio One under Studio One menu, Studio One Preferences...
The Keyboard shortcut is: Control , (Windows) Command , (Mac). (press Ctrl or Command and tap the comma key)
Is your StudioLive III setup correctly in there? Refer to:
