There seems to be no way of auto-generating "ducking" audio track keyframes. I can create clip keyframes ok.
Steps to reproduce:
1. In Essentail Sound, assign "Dialogue" and "Music" to a couple of clips on tracks.
2. Set the track containing the music to show Track Keyframes > Volume
3. Click on "Select Clips with Tag: Music" to select the music clip(s)
4. Click on "Generate Keyframes"
Result:
Nothing happens
Expected:
Track Volume keyframes should be generated
