grainSin nc tr dur freq pan envbuf

Granular synthesis with sine tones

nc - the number of channels to output. If 1, mono is returned and
     pan is ignored.

tr - a kr or ar trigger to start a new grain. If ar, grains after
     the start of the synth are sample accurate.

The following args are polled at grain creation time

dur - size of the grain.

freq - the input to granulate

pan - a value from -1 to 1. Determines where to pan the output in
      the same manner as PanAz.

envbuf - the buffer number containing a singal to use for the grain
         envelope. -1 uses a built-in Hanning envelope.
