2.    Once you click on the desired effect, a dialogue or settings box will appear. This will allow you to change the effect settings. For example: When using the echo effect, a dialogue box will appear asking you to change the Time Delay (seconds) and the Delay Factor. Changing these values will affect the way the echo sounds.
