This example shows the relationship between the Offset and the envelope's Attack
and Release2 stages. Notice that the envelope will always begin from the "0-plus-
Offset" level. Likewise, Release 2 will always end at the same level where the
envelope started. In this example, Offset is -35, shifting the envelope downward.
Thus the envelope starts below 0 and rises from there during Attack.
This example also shows how the envelope's Level is used to increase the amplitude
of the envelope when Offset is used. Since the Offset is set to
Level is set to
no stages above the 0 line can exceed that value.
The stage Levels do not behave exactly as they appear in the illustration. This is
because the envelope Level is set to
