linrand

linrand — Linear distribution random number generator (positive values only).

Description

Linear distribution random number generator (positive values only). This is an x-class noise generator.

Syntax

ares linrand krange
ires linrand krange
kres linrand krange

Performance

krange -- the range of the random numbers (0 - krange). Outputs only positive numbers.

For more detailed explanation of these distributions, see:

Examples

Here is an example of the linrand opcode. It uses the files linrand.orc and linrand.sco.

Example 202. Example of the linrand opcode.

/* linrand.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 linrand 1

  print i1
endin
/* linrand.orc */

        
/* linrand.sco */
; Play Instrument #1 for one second.
i 1 0 1
e
/* linrand.sco */

        

Its output should include a line like this:

instr 1:  i1 = 0.394
