Pencil tool
The Pencil tool allows you to draw pitch contours. It is selected using the contextual menu or by pressing M on the computer keyboard. or by pressing L on the computer keyboard. The cursor appears as the symbol shown, and can be applied by holding down the left mouse button and dragging between notes, at the desired pitch, to draw a new pitch contour. The tool only modifies the pitch values of blocks that exist. It cannot introduce pitch points where none was identified originally.
The result is a new pitch contour and pitch blocks that correspond to this contour.
