randomi — Generates a user-controlled random number series with interpolation between each new number.
Generates a user-controlled random number series with interpolation between each new number.
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.
Here is an example of the randomi opcode. It uses the files randomi.orc and randomi.sco.
Example 320. Example of the randomi opcode.
/* 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
