Some checks are pending
Check if Cog buildable / Build Universal Cog.app (push) Waiting to run
And disabled by default, at that. I can't actually hear the difference of Peak Extension in the Rock track I have that claims to use it. And Low Level Range Extension is more trouble than it's worth on tracks that use it by mistake, or maliciously, if the case may be. I may add track tag level control in the future.
