Example:
I have two groups, each has a tag: group1 = "tag1", group2 = "tag2". I need to control the volume of both.
I would assume that the following would work:
<binding type="amp" level="tag" identifier="tag1,tag2" parameter="AMP_VOLUME" />
Evidently, it's not possible to have more than one tag in an identifier. If there is, it stops working entirely. So how would I do this?
