Description

Generates is a controlled pseudo-random number series between min and max values.

Syntax

ares random kmin, kmax

ires random imin, imax

kres random kmin, kmax

Initialization

imin -- minimum range limit

imax -- maximum range limit

Performance

kmin -- minimum range limit

kmax -- maximum range limit

The random opcode is similar to linrand and trirand but sometimes I [Gabriel Maldonado] find it more convenient because allows the user to set arbitrary minimum and maximum values.

Examples

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

/* random.orc */
; Initialize the global variables.
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

; Instrument #1.
instr 1
  ; Generate a random number between 220 and 440.
  kmin init 220
  kmax init 440
  k1 random kmin, kmax

  printks "k1 = %f\\n", 0.1, k1
endin
/* random.orc */

        

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

        

Its output should include lines like:

k1 = 414.232056
k1 = 419.393402
k1 = 275.376373
