Adding audio compression across all clips STOPS Premiere Pro
Premiere is grinding to a halt once I add Multiband Processor (Broadcast) to all my clips in the timeline.
If I want to re-edit that video, I have to remove the Multiband Compression.
Both HD and 4K renders.

How many clips are you adding the audio effect to?
There is a known issue that is being worked on right now where Premiere will take a long time to start playback if there are hundreds or thousands of audio effects on clips in the timeline.
What you will see is when pressing the play button or pressing the space bar, the Transport will change from a triangle to a square, but the transport will not move. If you wait long enough, it will start moving. The length of time spend waiting is directly proportional to the number of audio effects you have.
As a workaround for now: If you are using the same effect with the same preset across all of those clips, you can add the effect as Track based effect, and remove the clip based effects. This will apply the effect to all clips on the affected track, so you must be more diligent about the placement of audio clips. The advantage is that instead of having hundreds or thousands of instances of the Multiband Compressor running in system memory, you will have just one for each track.
