Use ES2 Vector Envelope loop controls in Logic Pro for iPad
The Vector Envelope can run in one-shot mode, as long as the note is sustained; it can be set to repeat a specific number of times or it can repeat indefinitely, much like an LFO modulation. You can create repetitions with the loop functions.
Although the loop parameters seem similar to the loop parameters available for samples, there are significant differences between them. The Vector Envelope only supplies control signals that are used to move the gray dot positions of the Oscillator Mix pad and Mod 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 define several points that describe control point (gray dot) movements in the Oscillator Mix pad and the Mod Pad.
