I am not getting any audio from this patch. It's a direct copy of a practical from "Designing Sound" by Andy Farnell, 2010.

Specifically, this is the test patch for just testing the sound of an aluminum can that is tapped or struck. I am not getting sound whatsoever. I've checked audio preferences, tested other patches, and am thinking it must be an issue above my current knowledge base.

Thanks y'all
