Hi @Dlevhend,
Great question! Yep, you can drag and drop layers from the Library and reassign their input filter to match a drum in your setup. See the video below, where I go into the Library and drag a tom from Keine Zukunft into my working set (Black Cat Drums), and then adjust its input filter to Tom 3.
We’ve actually been discussing adding a 3rd tom to most sets in the Core Library and sound packs. Here’s version of the Core Library Acoustic Drums where we’ve done that.
