880 Chapter 39 Working in the Environment
Logic Pro maintains an internal list of all Environment objects. An object’s position in
the list is its Unique ID—as long as the object is not deleted, its Unique ID never
changes.
When objects are deleted, their position in this list becomes available for a new object.
Whenever an object is added to the Environment, it is placed in the first available
position on the list (if there are no empty positions, it is added to the end of the list).
 Import > Assign by Unique ID: Objects are assigned to objects from the source project
with the same Unique ID. This option is useful for updating an Environment when
objects have only been added.
 Import > Assign by Port/MIDI Channel: Objects are replaced by objects with the same
Port/MIDI channel. If a match can’t be found for an object, an object set to Port 0 and
the same MIDI channel is assigned. If a match still can’t be found, an object with the
same MIDI channel is assigned.
 Import > Assign by Name: Objects are replaced by objects with the most similar
name (At least 80% of the name must be the same).
 Import > Assign by Icon/Name: as above, except the object icons must also match.
The Environment Objects
This section covers each type of Environment object in detail, outlining what each is
designed to do, and how to use the parameters of the object.
Standard Instruments
Logic Pro provides standard instrument objects to handle MIDI devices that only use
one MIDI channel (typically, older synthesizers, MIDI controlled effect units or drum
machines). Standard instruments transmit MIDI data on a single MIDI channel.
To create a standard instrument, do one of the following:
m Choose New > Instrument (or use the New Standard Instrument key command).
