This example shows another relationship between the Offset and the envelope Level.
Since the envelope Level is set to 100, the level from the start of the envelope to the
maximum Output Level is 100. After the Offset is adjusted to +50, this pushes the
top half of the Attack segment beyond the maximum Output Level. The envelope
levels are calculated beyond the maximum, but are clipped at the maximum.
The HOLD function for the Release stage is also shown here. When the R2TIME is set
to its maximum value, it is set to HOLD mode. In this mode, when the envelope
reaches the Release2 Level, it holds at that Level infinitely until the Voice is released.
