470 Chapter 15 Matrix Editor
Quick Opening of Event or Score Editor
A double-click on any event (without any modifier) opens the Event editor. An Option–
double-click opens the Score editor.
Creating Notes
To create a note, click at the desired point on the background with the pencil tool.
Duplicating Notes
To copy an existing note to another position or pitch, first click the original note with
the pencil (near the middle).
Any notes now created by clicking the background will have exactly the same length
and velocity as the original note.
Deleting Notes
You can delete selected notes by pressing Backspace, or clicking on them with the
eraser.
Moving Notes
You can move selected notes by grabbing them (near the middle) and dragging them.
If you move notes vertically, they will be transposed, and if you move them horizontally,
they will be moved in time. The target position and pitch are shown in the help tag
while the mouse button is held down.
When you move notes horizontally, they snap to the division set in the Snap menu (you
can alter this setting at any time).
You can limit movement to one direction, to avoid accidentally transposing notes when
moving them vertically (and vice versa). (Options > Settings > Global Preferences: Limit
Dragging to one direction in Matrix and Score).
Setting a Finer Grid
When moving notes in the Matrix window, you can make fine adjustments at a high
resolution, by holding down Control as you drag. The exact resolution will depend on
the current Snap menu setting used in the window.
If you hold down Control-Shift, you can move the notes in tick steps, completely
independently of the Snap menu setting and the time grid.
