Trim notes in the Piano Roll Editor in Logic Pro for iPad
You can trim notes in the Piano Roll Editor to change their length (duration). Notes can be resized from either their start or their end point. You can trim individual notes or a group of notes together.
Trim notes by dragging
In the Piano Roll Editor menu bar, tap the Trim button
.Tap a note to select it, or select multiple notes.
Trim handles at the start and end of the note will appear. Depending on the note length, you might need to zoom in to the working area to make the handles visible.
Touch and hold one of the handles and drag it left or right.
Dragging the left handle will change the start position of the note and its length. Dragging the right handle will change the length of the note without changing its start position.
With the Pencil button 
selected, you can drag the left or right edge of a note to trim it even though there are no trim handles visible.
Tip: When you wait for a second after you touch and hold the note, the working area zooms in horizontally to let you adjust the start or end point more precisely.
Trim notes in the inspector
In the Piano Roll Editor menu bar, tap the Trim button
.Tap a note to select it, or select multiple notes.
Tap the Inspector button
on the left side of the view control bar (or press I on your external keyboard) to open the Note inspector.Tap the Details disclosure arrow to show the Details parameters.
Drag the Length value up or down, or tap the Length field to open the numeric input dialog and enter a numeric value.
With multiple notes selected, dragging the value up or down will change their length proportionally, and entering a value in the numeric input dialog will set all notes to that same length.
