krange -- the range of the random numbers (-krange to +krange)
For more detailed explanation of these distributions, see:

Here is an example of the bexprnd opcode. It uses the files bexprnd.orc and bexprnd.sco.
Example 46. Example of the bexprnd opcode.
/* bexprnd.orc */ ; Initialize the global variables. sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 ; Instrument #1. instr 1 ; Generate a random number between -1 and 1. ; krange = 1 i1 bexprnd 1 print i1 endin /* bexprnd.orc */
/* bexprnd.sco */ ; Play Instrument #1 for one second. i 1 0 1 e /* bexprnd.sco */
Its output should include lines like:
instr 1: i1 = 1.141
