Pressing Option/Alt on your keyboard during line entry will force the
current segment to be perfectly horizontal.
Only one pitch contour object (line or curve) can exist at any time point on
the Pitch Graph. When you complete the entry of a line object, any
object(s) that previously existed at the same time will be deleted.
The Curve Tool
The Curve Tool is used to draw arbitrary curves on the Pitch Graph.
Start the process by selecting the Curve Tool and clicking anywhere
on the Pitch Graph to set an anchor point. Hold down your mouse button
and move the cursor to draw the desired pitch contour curve. End the
process by releasing your mouse button.
Unlike the Line Tool, the Pitch Graph will not scroll if you attempt to move
the Curve Tool cursor outside the current display area.
Only one pitch contour object (line or curve) can exist at any time point on
the Pitch Graph. When you complete the entry of a curve object, any
object(s) that previously existed at the same time will be deleted.
The Pointer Tool
The Pointer Tool is used to select and drag existing target pitch
contour objects (yellow lines and curves).
The Pointer Tool behaves as follows:
• Clicking on the background of the Pitch Graph and dragging horizon-
tally selects objects’ anchor points. Shift-clicking extends the selection.
• Dragging beyond the Pitch Graph boundaries automatically scrolls the
graph.
• Moving the Pointer Tool over a pitch contour object causes the cursor to
change to the object cursor (a horizontal bar). Clicking on an
unselected curve or line segment with the object cursor causes
the curve or segment and its anchor points to become selected
and allows that object to be dragged. Clicking on an already selected
curve or line segment with the object cursor allows that object, along
with all other selected objects, to be dragged.
