The key map display consists of a number of separate areas that let you do different things:
This area at the top left displays the following information about the currently selected sample: Sample rate, mono/stereo information, bit resolution and file size.
This area at the left of the display displays the names of the samples in each zone. It also allows you to change the order of the zones by clicking and dragging them up and down.
This area, to the left of the Sample area, does not show any information. However, by clicking in it, you can instantly select all the zones that belong to a certain group.
Aside from the fact that this area at the top of the display is a guideline for setting up key ranges, it is also used for setting the root keys of, and auditioning loaded samples.
This area, situated just below the Keyboard area, gives you a visual indication of the key range of a selected zone. By clicking and dragging the "handles" at the key range boundaries, you can resize the key ranges, and by clicking in between the handles, you can move the key ranges without changing their length.
This area in the middle of the key map display is where you keep track of all the zones and the relationship between them. You can also move and resize the zones just like in the Tab Bar area, as described above.
There are both horizontal and vertical scrollbars that work just like regular scrollbars. Whenever there is more information in the key map display than what fits on a "single screen", you can use the scrollbars to reveal it. Either click on the arrows or click and drag the scrollbar handles.
