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.
Set the Vector Envelope Loop Rate
In Logic Pro, do one of the following:
Drag the green indicator in the center of the Loop Rate bar to the left or right.
Drag vertically in the value field “as set” (shown in the figure below).
Set a defined speed for the Vector Envelope loop cycle. You can also synchronize the
loop speed with the host application tempo.
As set: If you switch the Loop Rate to “as set,” the loop cycle length equals the sum
of the times between the sustain and Loop points. Click the field labeled “as set”
below the Rate slider to select it.
Rhythmic: If you set the Loop Rate to one of the rhythmic values (sync) by dragging
the Loop Rate indicator toward the left half of the slider, the loop rate follows the
project tempo. You can choose from 32 bars up to a 64th triplet note value.
Free: You can also set a free Loop Rate by dragging the Loop Rate indicator toward
the right half of the slider (free). The value indicates the number of cycles per
second.
Note: If Loop Rate is not switched to “as set,” and Loop mode (Forward, Backward,
or Alternate) is active, the times of points between the Loop and Sustain points and
the Loop Smooth value are shown as a percentage of the loop duration, rather than
in milliseconds.
Make smooth Vector Envelope loop transitions
In Logic Pro, drag to set a value for Loop Smooth. This evens out the transition from the
Sustain point to the Loop point in Forward or Backward loop mode.
If the Loop Rate parameter is set to Sync or Free, the loop-smoothing time is
displayed as a percentage of the loop cycle duration.
If the Loop Rate parameter is “as set,” the loop-smoothing time is displayed in
milliseconds (ms).
