Description

Generates a user-controlled random number series with interpolation between each new number.

Syntax

ares randomi kmin, kmax, acps

kres randomi kmin, kmax, kcps

Performance

kmin -- minimum range limit

kmax -- maximum range limit

kcps, acps -- rate of random break-point generation

The randomi opcode is similar to randi but allows the user to set arbitrary minimum and maximum values.

Examples

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

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

; Instrument #1.
instr 1
  ; Choose a random frequency between 220 and 440.
  ; Generate new random numbers at 10 Hz.
  kmin init 220
  kmax init 440
  kcps init 10

  k1 randomi kmin, kmax, kcps

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

        

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

        

Its output should include lines like:

k1 = 220.000000
k1 = 414.226196
k1 = 284.101074
