Drum Set's kick drum too soft

I’m trying to increase the volume of the kick drum in the Drum Set. I’ve managed to get to this dialog but everything below “Notehead set:” is disabled. I don’t want to change the notehead or the staff position.

If you’re using one of Dorico’s factory-supplied playback templates, you could choose to use one that will use Groove Agent SE for drum set playback (look in Play > Playback Template to see whether the chosen one has GASE in its name).

If you open the Groove Agent SE window, you can then click Mixer on the right-hand side, then Agent directly below, and you’ll then see a little mixer with separate faders for each drum, including the Kick.

That worked beautifully, thank you
