If you want the grain size in milliseconds, divide the Grain knob setting into 1000 - the knob’s range is 4 seconds to 6.67ms. The Grain knob’s range is 0.25 to 150 Hz, and just as a 100Hz analogue waveform means 100 cycles of the waveform per second, a 100Hz Grain setting means that 100 grains span one second.

The grain size is calibrated in Hertz (lower = longer), and you set it with the Grain knob in Granulator’s Grain view. Grains can be taken from anywhere within the audio file, and in Granulator their position and size can be modulated by various sources. Granular synthesis amounts to sequencing small slices (called grains) of an audio file while manipulating and processing them in various ways.
