Set up of your C4
A connected and powered Mackie C4 unit will be detected automatically when you open Logic
Pro. You can use the C4 in an independent control surface group (with other control surface
icons placed above or below the C4 icon), or combined in a group with one or more control
surfaces (such as the Mackie Control—place the icon to the right or left of the existing icons).
Although the C4 can be used independently, it is most useful when combined with other
control surfaces, particularly the Mackie Control. In this scenario, the C4 adds eight channels in
Mixer view. Using the C4 in its own control surface group allows you to edit instruments and
eects independently, while performing mixing and other tasks on the Mackie Control or other
control surface.
C4 V-Pots and V-Select buttons
The C4 provides 32 V-Pots, laid out in four horizontal rows.
•
The top row (row 1) consists of V-Pots 1 to 8.
•
Row 2 consists of V-Pots 9 to 16.
•
Row 3 consists of V-Pots 17 to 24.
•
The bottom row (row 4) consists of V-Pots 25 to 32.
Each V-Pot features an integrated V-Select button, which is activated by pressing the (V-Pot)
knob top.
The function or parameter assigned to each V-Pot/V-Select button depends on the current View
(see Use C4 views on page 181), and chosen overlay (see C4 Assignment buttons overview on
page 187).
•
V-Pots and V-Selects 1 to 8
When no overlay is active, V-Pots 1 to 8 (the top row) normally perform in the same way as
their counterparts on a Mackie Control or Mackie Control XT. See Mackie Control Assignment
buttons overview on page 60.
•
V-Pots and V-Selects 9 to 32
These V-Pots have additional functionality in dierent Views.
In Mixer (multichannel) views, the V-Pots in rows 2, 3, and 4 usually edit the parameter that
follows the parameter edited on row 1. For example, in Pan/Surround Mixer view, row 1 edits
the pan/surround angle, row 2 edits surround diversity, row 3 edits LFE level, and row 4 edits
spread.
In Channel view, all four rows represent a group of 32 editable parameters.
In Eect and Instrument Edit views, the C4 can be split into two groups (8/24, 16/16, or 24/8
parameters). See C4 function buttons on page 186.
