The description of envelope behavior just given is true when the
amount
param-
eter is set to a positive value. But since this control is actually bipolar, it is possible to
set a negative amount of modulation. In this case, the envelopes are inverted and their
behavior changes. The best way to get a feel for the difference is to experiment with
both positive and negative settings of the
env amount
parameter.
