Oh yeah that. But that bar is useless! It doesn't correspond to real-time, and like yorolpal said, it just goes from 0-100 after everything had already loaded!
I noticed a longer opening time for projects now. I don't know if that's because I'm using synths with larger patches now or what.
I think it's weird that EZ Drummer and some other synths (Broomstick Bass comes to mind) won't load the patch or kit if the synth is closed, you have to open the UI from the Synth Rack at least one time to "initialize" it.
