What Am I Doing Wrong with Groove Agent?

Why doesn’t my Groove Agent play when I input Key switch commands? It plays within Groove Agent, but when I want to have it play in a Dorico file, no cule… Totally confused, and I have used it for years!!!

When I load your document, there seem to be two issues:

  1. You’re not using Groove Agent as the VST for your drums.
  2. The version of HALion you’re using doesn’t seem to be the one I have.
