p0 = output start time (seconds)
   p1 = input start time (seconds)
   p2 = duration (seconds)
   p3 = amplitude multiplier (relative multiplier of input signal)
   p4 = grain rate (seconds)
   p5-8 = rate variance
   p9-12 = duration values (seconds)
   p13-16 = location values (0-1 stereo; 0.5 is middle)
   p17-20 = transposition values
   p21 = grainlayers [optional; default is 0]
   p22 = random number seed [optional; default is 0]

   Because this instrument has not been updated for pfield control,
   the older makegen control envelope sysystem should be used:

   assumes function table 1 is the amplitude envelope
   function table 2 is the synthesis waveform,
   function table 3 is grain amplitude envelope

   Parameters after the [bracket] are optional and default to 0 unless
   otherwise noted.

It was originally adapted from the older stgran Cmix instrument, also written by Mara.



Usage Notes

At present the setting of the buffer size in rtsetparams appears to have a significant effect on the output of this instrument.

STGRANR will take mono or stereo input files, it requires stereo output.



Sample Scores

very basic:

   set_option("FULL_DUPLEX_ON")
   rtsetparams(44100, 2)
   load("STGRANR")

   rtinput("AUDIO","MIC",2)

   makegen(1, 7, 1000, 1, 950, 1, 50, 0)
   makegen(2, 25, 1000, 1)

   start = 0.0
