Sampler Mapping and Zone panes in Logic Pro for Mac
You can use the Mapping and Zone panes to create and edit sampler instruments. The two panes are designed for different tasks, but work together to provide full control of individual samples, or zones, and their use within one or more collections of zones, known as groups.

A sampler instrument consists of zones and groups:
A zone is a location into which a single sample (an audio file) is loaded from hard disk. You can numerically edit all zone parameters in the Zone view. You can also edit basic zone parameters such as start, fade, and loop marker positions directly in the waveform display of the Zone pane.
Zones are assigned to groups, which provide parameters that you can use to simultaneously affect all zones contained in the group. You can define as many groups as required. You can numerically edit group parameters in the Group view.
You can easily assign zones to keyboard notes or note ranges in the Key Mapping Editor. In addition, you can graphically assign zones to velocity ranges in the Key Mapping Editor, making it easy to create multi layered sampler instruments.
See Create instruments with Sampler, Create Sampler zones, Create Sampler groups, and Sampler zone and group edits.
Switch between Mapping pane editors
The Mapping pane has three edit windows or views you can choose by clicking the buttons at the top right.
Key Mapping Editor button: Shows groups to the left, with zones arranged graphically across a keyboard in the Key Mapping Editor. See Use Sampler Key Mapping Editor.
Group view button: Shows groups and associated parameters in a column layout. See Use Sampler Group view.
Zone view button: Shows groups to the left, with zones and associated parameters in a column layout. See Use Sampler Zone view.
Menu bar: The menu bar at the top of the Mapping pane contains elements that are common to all editor views. See Mapping pane menu bar.
