Replicate will duplicate a sound or envelope to the number of times specified.
How to use it
Selecting Replicate from the menu will bring up a dialog box with Times as it's only parameter. The default parameter will duplicate the selection ten times.
The Times field can have a range of 1 to 99999999. If there is not enough memory to replicate the selection the specified number of times, it will do it as many times as memory allows.
