Pictured below is a multiple group example with two Mackie Controls, three
Mackie Control XTs, and one HUI:
The top row, consisting of the Mackie Control #1, Mackie Control XT #1, and
Mackie Control XT #2, forms a single control surface group with 24 channels. Mackie Control
#1 controls channels 1 to 8, XT #1 controls channels 9 to 16, and XT #2 handles channels
17 to 24.
In the second row, the Mackie Control #2 and Mackie Control XT #3 form a second control
surface group, controlling instruments (on channels 1 to 8) and auxes (on channels 9 to
16).
In the third row, the HUI forms a single unit control surface group.
Each group has individual settings, such as Flip mode, Display mode, Plug-in Parameter
Bank Offset, and others. This allows you to access, edit, and automate different sections
of the Logic Express Mixer.
In the example above, the three units in the top row could be used to control audio and
MIDI channel strips. In the second row, Mackie Control #2 could be used to control
instrument channel strips 1 to 8, and XT #3 could be used to control aux channel strips
1 to 8. The HUI could be used to edit group definitions. The physical placement of units,
and the way you use them, is completely flexible.
