Start using the CORRECT terminology. You are looking for a DELAY.
Set the plugin up as a SEND. Set the DELAY according to the TEMPO of your song AND notes (half, quarters, etc.) If you don't know what you are doing go and find a DELAY CHART. After you find the chart set the delay according to the numbers. If you don't like what you hear or you like it and want to fine tune it go ahead and AUTOMATE it.
