The MIDI Transform window in Logic Pro for Mac includes the following parameters and elements that can be used to process your MIDI data. See MIDI Transform window examples in Logic Pro.
These parameters globally affect the MIDI Transform window appearance and operating mode.
Global parameters
Presets pop-up menu: Choose one of the transform presets or one of your own transform sets.
Mode pop-up menu: Choose one of the following options to determine how events are transformed.
Apply operations to selected events: Applies the operations to all selected events. The selected events are determined by the selection conditions.
Apply operations and delete unselected events: Transforms the selected events, and deletes all unselected events. Only events that match the selection conditions remain after the transform operation. This mode allows you to use the MIDI Transform window as a programmable filter, where only events that match the conditions survive.
Delete selected events: Deletes all events that match the conditions, leaving all other remaining events unchanged. This mode allows you to use the MIDI Transform window as a programmable erase function. The operation settings are irrelevant in this mode.
Copy selected events, then apply operations: Retains the selected events in their original form, copies them, and applies the operations.
Options pop-up menu: Choose additional options from this menu.
Hide Unused Parameters: Hides all unused menus in the Selection Conditions and Operations areas. This provides a better overview of the settings in use. It also prevents you from making accidental alterations.
Relative Position: Position range values correspond to the start of the region.
Absolute Position: Position range values correspond to the start of the project.
Marquee selection defines position range: Position range values correspond to the events selected by the Marquee tool.
