For an in-depth study of these polarities, see our discussion on
using an LFO source as the example. This topic starts on page 155.
An interesting attribute of the envelopes is that while they rely on a trigger source to
start (an envelope is a trigger destination), they themselves can also be trigger
sources. One of the more interesting properties of envelopes is the triggering
capabilities of the envelopes' parameters. As an example, an envelope can be
configured so that a trigger is generated by an envelope when its attack stage reaches
a certain level. This trigger can be used to start another envelope or an LFO as just a
few possibilities.

"moving in a negative direction." This means
that a trigger is generated when the

decreasing in amplitude.
