Chapter 3 ES2 73
Set up Vector Envelope loops
The Vector Envelope can run in one-shot mode, as long as the note is sustained; it can be set to
repeat a specic number of times or it can repeat indenitely, much like an LFO modulation. You
achieve repetitions by using the loop functions.
Although the loop parameters seem similar to the loop parameters available for samples, there
are signicant dierences between them. The Vector Envelope only supplies control signals that
are used to move the pointer positions of the Triangle and Planar Pad. The audio output of the
ES2 is not looped in any way.
Any point can be declared the Loop point. Provided that the note is held for a suitable length of
time, portions of the envelope can be repeated, or looped.
The looped area spans the time between the Sustain point and the Loop point. In between these
points you can dene several points that describe pointer movements in the Triangle and the
Planar Pad.

A Loop point is indicated by an L in the strip below.
Set a Vector Envelope Loop mode
m Choose one of the following Vector Envelope Loop modes: O, Forward, Backward, and Alternate.
•
O: When Loop mode is set to O, the Vector Envelope runs in one-shot mode from beginning
to end, if the note is held long enough to complete all envelope phases. The other loop
parameters are disabled.
•
Forward: When Loop mode is set to Forward, the Vector Envelope runs from the beginning
to the Sustain point, and then begins to periodically repeat the section between the Sustain
point and the Loop point in a forward direction.
•
Backward: When Loop mode is set to Backward, the Vector Envelope runs from the beginning
to the Sustain point, and then begins to periodically repeat the section between the Sustain
point and the Loop point in a backward direction.
•
Alternate: When Loop mode is set to Alternate, the Vector Envelope runs from the beginning
to the Sustain point and then periodically switches to the Loop point, then back to the Sustain
point, alternating between backward and forward directions.
