Envelope POLAR POSWAV
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
-35 and the envelope
Level is set to 100 , the Attack Stage actually reaches its maximum point at +65 , and
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 100 and the Offset to -35 . For example, Decay 2
Level is set to 79 (more than 3/4 between 0 and the maximum). But because it is
Offset by -35 and amplified by 100 the the resulting level (internally calculated) is
about 60 where it appears in the illustration.
