Quantize Value: Set the Quantize value in the key focus window.
Division: Set the Division value in the key focus window.
Horizontal Zoom: Set the horizontal zoom level in the key focus window.
Vertical Zoom: Set the vertical zoom level in the key focus window.
Channel Strip: Choose to use an assignment to set a channel strip parameter. A Channel Strip pop-up menu appears below the Class pop-up menu, showing the following parameters.
Selected track: Corresponds to the selected track except when the control surface group’s Track Lock parameter is active. In this case, the selected track is the track chosen when Track Lock was enabled.
Fader Bank: Addresses a channel strip in the control surface group’s current View (Arrange, All, Tracks, Single). This is dependent on the current Fader Bank value for this mode. For example, if the View is All, the All view Fader Bank is five, and the number next to this parameter is two. Thus, the eighth channel strip in the All view is addressed (Fader Bank and No. are zero-based, so add 1).
Index: The index number of a channel strip in the Mixer, independent from channel strip type, as counted from the left end of the Mixer. The index number also includes channel strips without track numbers, such as auxiliary tracks. The index number changes as track order (and with it, channel strip order in the Mixer) changes.
Audio: An audio channel. The numerical value (No.) determines which audio channel is addressed (zero-based; to address audio channel 2, use a value of 1).
Software Instrument: A software instrument channel. The numerical value (No.) determines which channel is addressed (zero-based; to address channel 2, use a value of 1).
Bus: A Bus channel. The numerical value (No.) determines which channel is addressed (zero-based; to address Bus 2, use a value of 1).
Auxiliary: An Aux channel. The numerical value (No.) determines which channel is addressed (zero-based; to address Bus 2, use a value of 1).
Output: An Output channel. The numerical value (No.) determines which channel is addressed (zero-based; to address Bus 2, use a value of 1).
Master: The Master channel strip; if it does not exist in the project, the first output channel strip is addressed.
If you choose the Fader Bank, Index, Audio, Software Instrument, Bus, Auxiliary, Output, or Master setting from the Channel Strip pop-up menu, the following two parameters become available:
Number field: The channel strip number defines the number of the controlled channel for the selected channel strip type.
Parameter field: Text description of the addressed parameter. Can only be set by choosing the Logic Pro > Control Surfaces > Learn Assignment for [parameter name] menu item. Note that for plug-in and instrument parameters, Parameter Page offsets apply, allowing you to shift parameter addressing up and down by page.
Key: Choose to use assignments to emulate computer keyboard keystrokes. You can enter the key to emulate in the Key field, which appears below the Class pop-up menu. This is not case-sensitive.
Key Command: Choose to use an assignment to perform a key command. You can enter the key command in the Command field, which appears below the Class pop-up menu. Some key commands provide on/off or enabled/disabled feedback.
If you want to execute your key command assignment repeatedly, select the Key Repeat checkbox at the bottom of the Controller Assignments window. For further information, see Apple Books | Apple Books | PDF
