Cropping Music:

The end of a piece of music can be cropped , as can the beginning. The process is the same.

Clicking on the purple music track highlights it in deeper purple, allowing you to make changes.

If the music is too long - as in the diagram - the end can be cropped.

This is done by clicking and dragging the black triangle to the desired point.

You should then pull down the Edit menu and select Crop.

The unwanted part is deleted, as shown here.
