SampleTank 3 - Edit MIDI PATTERNS in Pro Tools

Hi question how didi you install sampletank 3in pro tools and wthat version i got pro 10.39 but shows samletank 2 but no samples inside tks

Thanks for these vids on ST3.  I'm a newbie, found them very helpful.

Maybe I'm over thinking this, but is there a need to ever save patterns and then load them back into ST3 once you've finished editing them? If so, how would you do that?
