Modifier Buttons
The four Modifier buttons correspond to the modifier keys on your computer keyboard
(but function independently from them). You can use these buttons, along with the
appropriate key on your computer keyboard (or with the mouse), instead of using the
corresponding modifier key. This also applies to the modified Mackie Control
commands (as covered in each function description).
A generic description of each Modifier button follows:
 SHIFT: Provides an alternate function or meaning for a button.
 OPTION: The function applies to all channel strips. For relative value changes, sets
the parameter to its minimum, default, or maximum value—depending on whether
youre increasing or decreasing it.
 CONTROL: While held down, the group clutch is engaged—channel strip groups are
temporarily disabled.
Âx/ALT: Allows fine tuning, or another variation, of the function.
Automation Buttons
The Automation buttons activate the corresponding automation modes in
Logic Express: Read/Off, Touch, Latch, and Write. You use the Automation buttons in
conjunction with the channel SELECT buttons, as follows:
To set the automation mode for a channel:
1 Select the channel you want to automate.
2 Press the desired Automation button to assign the mode you want to use.
3 Move the corresponding fader.
The automation modes are outlined below:
 READ/OFF: If no automation mode is active, pressing the READ/OFF button toggles
between Read mode and Off.
 Read: The fader reads (follows) any existing automation data, but does not record
any new automation data.
 Off: Automation is off. The fader neither sends, nor receives, automation data.
Existing automation data is not changed. The fader still adjusts the volume or pan
position as per usual, when moved.
 TOUCH: Writes new data when the fader is touched or the V-Pot is turned during
playback. Any existing automation data (of the current fader type) is replaced with
new data, for as long as the control is active (while the fader is being touched or the
V-Pot is being turned).
