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.
