• LATCH: Similar to Touch mode, but the control remains active, even when the fader is
no longer being touched, or the V-Pot is not being turned. When you release the fader,
the current fader value replaces all existing automation data, for as long as the sequencer
is in playback (or record) mode. Press STOP to prevent existing automation data from
being overwritten.
• WRITE: Overwrites all existing automation data, or creates new automation data if none
exists. Only use this option if you want to destroy all existing automation data.
Pressing one of the Automation buttons while holding down the OPTION button assigns
the selected automation mode to all channels. When an automation mode has been
assigned to all channels, the corresponding automation mode button LED illuminates
whenever you hold down the OPTION button.
Important: This behavior is slightly different for the Off automation mode. When holding
down the OPTION button and pressing Read/Off, the LEDs for the other Automation
buttons are unlit, but this does not necessarily indicate that all channel strips are in Off
mode—they could still be set to other modes. To ensure that you have set all channel
strips to Off mode, press Read/Off twice while holding down the OPTION button. The
Read/Off button LED turns on, then off.
Mackie Control: GROUP Button
Pressing the GROUP button activates Group Edit mode, allowing you to edit various Mixer
group parameters.
In Group Edit mode:
• The upper row of the LCD displays channel strip names.
• The lower row of the LCD displays group parameters.
• The Assignment display shows the currently displayed group—G1, for example.
• The Time display shows the group name. (If the name is longer than ten characters,
the last ten characters are displayed.)
• You can switch between group parameters with the V-Pot buttons.
• The Cursor Up and Cursor Down buttons select the previous or next group.
• The Cursor Left and Cursor Right buttons shift the group parameter display.
• The SELECT buttons determine group membership. Pressing a SELECT button adds the
channel strip to the group (or removes it from the group, if already a member). An
illuminated SELECT button LED indicates active group membership.
• The LED next to the GROUP button is illuminated.
Note: Ensure that the ZOOM button isn’t active when using the cursor buttons.
