Moving the Pointer Tool over a pitch contour object anchor point
(whether that point is currently selected or not) causes the cursor to
change into the anchor point cursor (four diagonal arrows).
Clicking on an anchor point with the anchor point cursor deselects
all other objects and anchor points and selects that anchor point
so that it can be dragged. Dragging an anchor point stretches or
compresses the pitch contour object relative to the nearest unselected
anchor point(s).
The extent to which you can drag selected objects is constrained by the
position of neighboring unselected objects.
In some host applications, holding down the Option/Alt key and then
clicking to drag will restrict the cursor to vertical movements only
(the cursor will change to indicate this state). The effect of this is
to allow you to modify the pitch contour while preserving the
objects location in time. This is particularly handy after using the
Make Curve button, discussed below.
Clicking on the background of the Pitch Graph de-selects all selected
objects.
While the above may seem a bit mind-boggling on first reading, in prac-
tice its quite intuitive. Spend a minute or two playing with the Pointer
Tool and all will become clear.
The Zoom/Select Tool
The Zoom/Select Tool serves two purposes, depending on whether it
is used in the Pitch Graph or the Envelope Graph.
In the Pitch Graph, use the Zoom/Select Tool to click and drag a box
around an area of interest. Dragging off the Pitch Graph automatically
scrolls the graph. When you release the mouse button, the scale and
position of the Pitch Graph will be changed to display the area enclosed
by the box.
In the Envelope Graph, click and drag with the Zoom/Select Tool to select a
range of time containing audio. This causes the Make Curve button to
become active (see below). Clicking Make Curve will create a pitch contour
curve with anchor points at the selection boundaries.
Note: The Zoom/Select Tool can also be used to add new anchor
points in the middle of an existing curve previously created by
the Make Curve function. Simply select a range of time such
that one or both boundaries of your selection fall at the
point(s) where you would like a new anchor point and then
click Make Curve. Voilá.
