Scrollbar and Zoom control on Pitch Trace Display

The Scroll Bar and Zoom buttons on the right-hand side of the Pitch Trace display allows you to change the range of pitch displayed.

Scroll

Click on the scroll-bar with the mouse pointer and slide it up or down, or click on the arrows at each end. This will change the range of pitch displayed, but will not alter the number of notes shown in the display.

Zoom

Click on the magnifying icons - the large one to zoom in, and the small one to zoom out. This will decrease (zoom in) or increase (zoom out) the number of notes displayed.

You can also click on the separator-bar, and hold the (left) mouse button down. By moving the pointer up or down, you then have a continuous adjustment in the range of notes displayed, ranging from a single note to the entire range.
