Can't read anything in those first two screen shots. Can you post larger PNG not JPG flies? What track is the synth input supposed to be on in Pro Tools?

Your Playback Engine is set to the Apollo? And everything else works OK right?

Why is the Setup>IO showing aggregate IO? Are you using that or the Apollo? What exactly is Setup>Playback Engine set to? It should be the Apollo *not* aggregate IO. Then in Setup>IO Go to each page select all the IO paths. Click delete. The click Default. Now go back and set up all the track IO inputs and outputs to be what you want them to be.
