Uniform distribution random number generator (positive values only). This is an x-class noise generator.
krange -- the range of the random numbers (0 - krange).
For more detailed explanation of these distributions, see:

Here is an example of the unirand opcode. It uses the files unirand.orc and unirand.sco.
Example 395. Example of the unirand opcode.
/* unirand.orc */ ; Initialize the global variables. sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 ; Instrument #1. instr 1 ; Generate a random number between 0 and 1. ; krange = 1 i1 unirand 1 print i1 endin /* unirand.orc */
/* unirand.sco */ ; Play Instrument #1 for one second. i 1 0 1 e /* unirand.sco */
Its output should include lines like this:
instr 1: i1 = 0.840
