Vector Envelope points, times, and loops
Use Vector Envelope points
The Vector Envelope time axis runs from left to right.
Vector Envelope
time axis
Point 1
Sustain point is shown
on row above time axis.
Loop point is shown on
row below time axis.
Point time value shown
in milliseconds (ms).
Up to 16 points can be displayed on the time axis (10 are shown in the figure above). Each point
can control the pointer positions of the Triangle and the Planar Pad.
The points are numbered sequentially, from left to right, along the time axis.
There are always at least three points: point 1 is the start point, point 2 is defined as the Sustain
point, and point 3 is the end point.
Any point can be declared the Sustain point. If a played note is held for a sufficient length of
time and there’s no loop engaged, any envelope movement stops when the Sustain point
is reached. The Sustain point value is maintained until the key is released—until the MIDI
note-off command.
Any point can be declared the Loop point. The looped area spans the time between the Sustain
point and Loop point. In between these points you can create additional points that describe the
movements of the pointers in the Planar Pad and Triangle.
The more points you set, the more complex the movements that can be performed.
Select a point
mm
Click the point to select it.
Once selected, you can edit the point.
Create a new point
mm
Shift-click between two existing points.
The segment that previously existed between the two old points is divided at the clicked
position. The sum of the two new segment times is equal to the time of the original undivided
segment. This ensures that any points that follow retain their absolute time positions. Existing
pointer positions in the Triangle and Planar Pad are fixed, thus ensuring that newly created
points don’t affect any previously defined movements.
