The frequency of grains per second. The rate at which data from the stored function table ifna is read within each grain. This has the effect of transposing the original material. A value of 1 produces the original pitch. Higher values transpose upwards, lower values downwards.
Negative values result in the function table being read backwards.
The rate at which successive grains advance through the stored function table ifna . This determines the movement of a pointer used as the starting point for reading data within each grain. The operation of this parameter is identical to that in fof . Their operation is identical to that of the local envelope parameters in fof .
