• Descending Bar: A bar from the top to the current value.
• Text Only: LED rings: no feedback; LCDs: no feedback as a graphics element.
• Automatic: Dependent on the currently assigned parameter, the most suitable feedback
mode is used: Plug-in and Instrument parameters carry this information, Pan displays
a Single Dot/Line, and all other parameters display a bar that runs from left to right
(Left to Right Bar).
Note: Feedback only works for supported control surfaces, and not all settings are available
for all controls.
Text Feedback Checkbox
When selected, a text representation of the current value is sent to the control surface’s
display. The control surface display capabilities determine the display position and number
of characters that are used.
Local Feedback (Fader/Knob) Checkbox
When selected, no feedback is sent while the parameter is in Touch mode. This prevents
motorized faders from “fighting” against the user.
Key Repeat Checkbox
When selected, the assignment is repeatedly executed. The Key Repeat Rate slider—set
in the Mac OS X Keyboard & Mouse preferences—determines how quickly Logic Express
repeats the assignment. The duration that the button/controller must be held for, before
the assignment is repeated, is set with the Delay Until Repeat slider in the Keyboard &
Mouse preferences.
Key Repeat is particularly useful for the zoom function. For example, if you assign a Key
Repeat command to the Mackie Control Zoom buttons, holding down the Zoom In button
will continuously zoom in the Logic Express window until the button is released. This
mirrors the behavior of the Zoom key commands. The alternative is to repeatedly press
the (Mackie Control) Zoom buttons to zoom in or out more than one level.
Note: The Key Repeat checkbox is only available for key commands, key presses, and
relative value changes. If any other assignment class is selected, the checkbox is dimmed.
The default key command assignments support the Key Repeat function (if useful or
applicable to the control surface or device), making changes unnecessary for use of this
functionality.
If you want to enable the Key Repeat function for your own assignments, you may need
to use the re-learn option for the assigned message. Key Repeat messages must include
the Lo7 byte, which provides information on the up (released) or down (pressed) state
of the assigned button.
