 The above fits three samples into the pattern, i.e. for the first cycle this will be `"bd"`, `"sn"` and `"arpy"`, giving the result `"bd [~ sn] arpy sn"` (note that we start counting at zero, so that `0` picks the first value). The following cycle the *next* three values in the list will be picked, i.e. `"arpy:1"`, `"casio"` and `"bd"`, giving the pattern `"arpy:1 [~ casio] bd casio"` (note that the list wraps round here).
