Loop Sculpture envelopes in MainStage

The envelope can run in one-shot mode, like any envelope—the envelope phases run for as long as the note is held. It can also run through each phase several times or in an infinite cycle, much like an LFO. You can achieve this through the use of loops.

You can synchronize loops to the project tempo automatically by using the sync and ms buttons.

When you are in any of the loop modes, the loop always cycles between user-defined envelope handles that indicate the Loop start point (L icon), and the Sustain point (S icon). You can drag these handles to any position.

• When set to Finish, the envelope runs in one-shot mode from beginning to end—even if the note is released before all envelope phases have completed. The other loop parameters are disabled.

• When set to Loop Forward, the envelope runs to the Sustain point, and begins to periodically repeat the section between the Loop and Sustain points—always in a forward direction.

• When set to Loop Backward, the envelope runs to the Sustain point, and begins to periodically repeat the section between the Sustain and Loop points—always in a backward direction.

• When set to Loop Alternate, the envelope runs to the Sustain point, then periodically returns to the Loop point and back to the Sustain point, alternating in both a backward and forward direction.
