Move notes in the Piano Roll Editor
You can move selected notes in the Piano Roll Editor to change their time position. When you
move notes, they move according to the current Snap value for the Piano Roll Editor.
When you drag a note, a help tag shows its current time position and pitch. Its deviation from
the starting pitch is shown as a positive or negative value.
You can also move notes using an Event Float window. For information, see Event Float window .
Tip: The info display in the Piano Roll Editor menu bar shows the note name and time position
under the pointer. Watch the info display as you move notes to ensure that you move them to
the correct position.
