+## beatRepeat
+
+A beatrepeating effect (sometimes called stutter) that continuously repeats a section of the entire sound that was last played. The repating interval is determined in divisions (`1/4`, `3/16`, etc). It immediately starts repeating at the moment of evaluating the code, so timing is key!

 ## osc
 
 Set the ip-address, in-port and out-port number for the network to transmit OSC-messages over using UDP. Default settings are 8000 (in-port), 9000 (out-port), localhost (127.0.0.1) (ip).
