BUG: audio ducking crashes premiere if dialogs have dynamics or EQ
If you apply dynamics under clarity tab on essential sound panel, and then try to duck the music against the dialog by hitting the "Generate Keyframes" button, premiere instantly crashes. Happens on 12.1.1 on a new project, after reset with default settings and default layouts.

This issue should be addressed in the Premiere Pro 12.1.2 update that was just released.

I see this issue and in addition. when reopening a project that has had audio ducking applied, the keyframes are visually in place, but no action is taken on the sound level, i.e. transition from 0db to -18db over 18ms can be seen on the main audio track, but it has no effect on the sound level. Toggling the solo button or regenerating the keyframes fixes the issue if it doesn't crash.
