We updated the Concrete Limiter today so it now works on Command Center and we have also resolved a known issue for some customers where the output of the limiter would be silent after saving and reloading a project.
 
Go to your Command Center to get the update. 

Great news!! Thanks for the heads-up, Andrew.

Nice Thanks.

I do not see this in Command Center
 

Works great- but there is some weird behavior: I have one instance on a bass channel (audio) and a second instance on the 'master channel'. The bass instance has the "bass enhancement" button in the "off" (o) position. The master instance has it in the "on" position (i) . Everything seems to be working fine.
 
The problem: when I try rendering the project (export as MP3), the "bass enhancement" buttons switch positions!!!!! Pretty weird - and have not had time to determine whether it affects audio (the exported Mp3) or not.
 

Hey Irvin,
 
I haven't heard of this issue and gave it a try myself and don't see the button changing positions for me. This an existing project that already contained the Concrete Limiter? Could you try removing both instances and re-adding it and then doing another bounce?
 

Thank you.....that's two nice little updates today!  I'm likin' it!

I tried the bass expansion swap thing and have a theory on what you saw, since it almost fooled me. 
 
The track inspector will switch what ProChannel strip it's showing based on the track selection focus.  After I rendered, the Master bus's ProChannel took the place of the audio track's ProChannel in the inspector. And like magic the Bass switch looked like it turned on, but my two strips had other differences which made me realize that the Inspector wasn't looking at my audio track anymore, but it was subtle and easy to miss.  Selecting each track showed the settings hadn't changed.
 

Ah, great fix. I've recently run into this problem on a project where I have multiple CLs. This is going to save me a lot of restarts over the next few weeks.

Thanks Andrew!
