Apple Logic Express 9 - Manual (Page 735)

• Delete selected events: Choose this mode to delete selected events. This mode allows
you to use the Transform window as a programmable erase function. All events that
match the conditions are deleted, and all other events remain unchanged. The
operation settings are irrelevant in this mode.
• Copy selected events, then apply operations: Choose this mode to retain the selected
events in their original form, copy them, and apply the operations.
• Presets menu: Choose one of the transform presets or one of your own transform sets.
• “Hide unused parameters” checkbox: 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.
Defining Selection Conditions
You can define conditions that determine which events are selected for transform
operations. This is done in the Selection Conditions area of the Transform window.
Each column represents a different MIDI event parameter.
• Position: Determines the time position of the event, referenced to the start point of
the MIDI region (not the start point of the project).
• Status: Determines the event type.
• Channel: Recorded MIDI channel of the event
• Data Byte 1/Pitch: First data byte (controller number) or note pitch
• Data Byte 2/Velocity: Second data byte (controller value) or note velocity
Note: The parameters displayed in the Data Byte fields are dependent on the chosen
Status menu setting. Certain Status menu settings will not show the Data Byte fields
at all.
• Length: Length of the note or event
• Subposition: Time position of the event, within a bar
The condition is considered to be fulfilled when an event matches the defined effective
range, and values, of all event parameters. These ranges and values are determined in
the pop-up menus and fields found under each of the event parameter columns.
To choose the event type
µ
Click the Status pop-up menu to determine which events will be selected. You have a
choice of two settings:
• All: All event types fulfill the condition.
• =: A further pop-up menu is displayed below the Status pop-up menu, in which you
can define the desired event type. These include note, poly pressure, control change,
program change, channel pressure, pitch bend, meta, and fader.
