Chapter 20 ES2 245
Default Setting of the Vector Envelope
The default setting of the vector envelope consists of three points. Point 1 is the
startpoint, point 2 is defined as the sustain point, and point three is the end point, by
default.
The impact of the vector envelope on the Oscillator Mix Triangle or on the Square is
switched off by default. This allows the ES2 to behave as a synthesizer without a vector
envelope generator. This traditional starting point is more convenient when creating
patches from scratch.
There are two ways to switch off the vector envelope:
 You can switch on the Solo Point parameter (described on page 246). If it is on, only
the Triangle and Square cursor positions of the currently selected point are active.
 You can disable the vector envelope altogether (or only the Triangle or Square) as
described in the “Vector Mode Menu” on page 241.
Setting and Deleting Points
The more points you set, the more complex the vector envelope movements that can
be designed. You can:
 Create a new point by Shift-clicking between two existing points. The segment that
previously existed between the two old points is divided at the mouse position. The
sum of the two new segment times is equal to the time used by the old undivided
segment. As such, the ensuing points retain their absolute time positions. In addition,
the existing cursor positions in the Triangle and Square are fixed, ensuring that the
creation of new points does not affect any previously defined movements.
 Delete points by clicking on them while holding Control.
Setting Vector Envelope Times
By clicking a time value and moving the mouse, you will alter the envelope time—the
time it takes for the vector envelope to travel from the point before this time value to
the point after this time value. You have two ways of doing this.
 Simple vertical dragging of the time parameter results in reaching all following
points later (or sooner, respectively) in time.
 Dragging with Control held, you will shorten or lengthen the time of the following
point by the same amount. This ensures that the adjacent, and all following, points
retain their absolute time positions.
Resetting the Values of a Point
Reverting to default cursor positions in the Triangle and the Square is done by:
 Clicking in the Triangle while holding down the Option key. This sets all Oscillators to
output the same level. The cursor is set to the middle of the Triangle.
 Clicking onto the Square while holding down the Option key sets the cursor to the
center of the Square. Both axis values are set to zero.
