You import an Environment into Logic Pro using an Environment patch. A single-purpose Environment patch might be an editor for a specific piece of MIDI equipment, an Environment for a single MIDI processing task (such as a MIDI LFO), or a complex arpeggiator/delay line configuration.
Choose Options > Import Environment > Layer, then choose a layer in the dialog that appears.
This layer—including all objects in the layer—is inserted in the destination project, at the same layer position (the same place in the Layer pop-up menu) that it occupied in the source project. Any existing layers are shifted as needed.
You can also move Environment objects (including cabling) between projects by dragging, or by copying and pasting. To make this even simpler, you can combine the objects into a macro.
Choose Options > Import Environment > Merge.
All Environment objects from the source project are added to the Environment of the destination project. Merged objects are placed in the same layer as their source, which can create a mess if objects already occupy that layer in the destination project. To avoid this issue, create blank layers (in the destination project) at the same layer positions of the source project, before importing.
When importing an Environment patch in this way, be careful of the following:
If unique objects in the Environment, like the Physical Input and Sequencer Input objects, are imported, they will replace their counterparts in the destination Environment and any cables leading into them will be lost. It’s best to temporarily delete these from the source Environment before importing.
When you import an object, all objects cabled from the imported object are also imported.
