Creating Nested Templates
You can create templates that contain other templates. Combining templates this way allows you to specify separately for each child template whether you want to use its parameter values in the parent template or whether you want to use fixed parameter values.
A good example for nested templates is the definition of a group of four knobs as ADSR envelope controls.
Procedure
Result
You created the nested Template ADSR Knobs. When you use the ADSR Knobs template, the labels will always be A, D, S, and R, but the knobs can be freely connected to any envelope.
