Modulation
The concept of controlling one parameter by another one is called modulation. HALion offers many fixed assigned modulations, such as the amplitude and filter envelopes, or pitch key follow.
Modulation assignments can be set up in the modulation matrix or using the modulation assignment rows in the Zone Editor.
In the Zone Editor, parameters that can be modulated are indicated by a small white triangle. If a modulation source is assigned to a parameter, the triangle of this parameter turns orange.
