Mackie C4: Function Buttons
This section outlines the FUNCTION buttons at the lower left of the C4 control surface.
SPLIT Button
Splits the C4 rows as follows: 4/0, 1/3, 2/2, and 3/1. This is known as a Split Edit, and allows
you to simultaneously edit two separate sections of a plug-in, or even two different
plug-ins.
Split Edit is also possible across multiple C4 units. For example, with two C4 devices,
pressing the SPLIT button offers the following split modes:
• 1/7 (Split Upper is top row of first C4 unit; Split Lower is bottom 3 rows of first unit and
all rows of second C4 unit. LED 1/3 is lit.)
• 2/6 (Split Upper is top two rows of first C4 unit; Split Lower is bottom two rows of first
unit and all rows of second C4 unit. LED 2/1 is on.)
• 3/5 (LED 3/1 is on.)
• 4/4 (All three LEDs are on.)
• 5/3 (All three LEDs are on.)
• 6/2 (All three LEDs are on.)
• 7/1 (All three LEDs are on.)
LOCK Button
Activates/deactivates Track Lock. When LOCK is enabled, selection of a different track in
the Arrange window does not switch the current track/channel selection on the C4.
SPOT ERASE Button
Unassigned
