Does a nice job of syncing with timeline and remetering. Probably overkill for most though.
It does show up the multichannel / adaptive track limitations of Premiere Pro though (only A1 is processed when plug-ins added to master bus of a multichannel sequence, or an adaptive sub-mix bus). Instead of stereo meters within the plug-in it becomes mono metered (as the plug-in is being fed only 1 audio track).
NB the AU plug-in works best in PP. The VST one crashes PP and the VST3 one has UI display issues.
