The Label fields contain the labels that you defme in the Timing
Format Specification menu. If there are more labels than can fit on
screen, use the left/right ROLL key and the KNOB to view those that
are not displayed.

Each label has its own base defmed separately from the other labels. If
you select one of the Base fields, you will see the following pop-up
menu. Decide which base you want to define your pattern in and select
that option.
