The idea here is to make closed feedback loop with arbitrary processing in the loop. To achieve this, a p-value is written to at the end of the loop, and read from at the beginning of the loop with some dry sound (plucks) mixed in.
Here are some Sporth learning resources (most of them by Paul Batchelor):
