well if it is a pause, then you can just cut it into frames for however long of a pause you wish to obtain. Otherwise it is still just making a variation to the loop. You can just edit the last section of a loop with a Reverse edit, filter, delay or whatever else is desired. Hopefully this is easy to understand. If not, please just keep asking and I'm sure the communication path will be there as we understand one anothers way of thinking.
