Apple Logic Pro 9 - Manual (Page 715)

If a parameter of one of several selected events is altered, it affects the same parameter
in all events within the selection group. When you alter parameter values in a group of
selected events, the relative differences between parameter values remain unchanged.
Parameter values can only be altered until the (same) parameter value of one of the
selected events has reached its maximum or minimum value.
To override the maximum or minimum value limitation
µ
Option-drag the value, or press Return to confirm a numerical input.
This allows you to continue altering a parameter value in a multiple selection, even when
one of the selected events has reached its maximum or minimum value.
To set a parameter to the same value for all selected events
µ
Hold Shift-Option while using the mouse as a slider, or press Return to confirm a numerical
input.
Note: It is possible to select different event types, and simultaneously alter the Num(ber)
or Val(ue) parameters. Needless to say, this can lead to unexpected, and disastrous, results.
It is highly recommended that you make use of the event filtering buttons to hide
nonmatching event types. The enhanced selection functions may also be of use when
creating or editing groups of events.
Deleting and Muting Events
These two functions go hand in hand, since you will often want to remove events that
you have muted.
To mute or unmute a note event
µ
Click a note event with the Mute tool.
A dot appears in the Status column of muted note events.
The Edit > Select Muted Regions/Events command is also available in the Event List. It
allows the selection of all muted notes in a MIDI region, making them easy to delete.
To delete events
Do one of the following:
µ
Click them with the Eraser tool.
µ
Select the events, and press Delete.
µ
Choose one of the commands in the Functions > Delete MIDI Events menu.
• Duplicates (default key command assignment: D): Erases all duplicate events.
• Inside or Outside Locators: Erases all MIDI events within/outside the locators.
• Outside Region Borders: Erases all MIDI events that completely fall outside the region
borders, which can happen when regions are resized.
