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 1. Example of the randomi opcode.
