randi randi rand Generates a controlled random number series with interpolation between each new number. Generates a controlled random number series with interpolation between each new number. ares randi xamp, xcps [, iseed] [, isize] [, ioffset] kres randi kamp, kcps [, iseed] [, isize] [, ioffset] iseed (optional, default=0.5) -- seed value for the recursive pseudo-random formula. A value between 0 and +1 will produce an initial output of kamp * iseed. A negative value will cause seed re-initialization to be skipped. A value greater than 1 will seed from system time, this is the best option to generate a different random sequence for each run. isize (optional, default=0) -- if zero, a 16 bit number is generated. If non-zero, a 31-bit random number is generated. Default is 0. ioffset (optional, default=0) -- a base value added to the random result. New in Csound version 4.03. kamp, xamp -- range over which random numbers are distributed. kcps, xcps -- the frequency which new random numbers are generated. The internal pseudo-random formula produces values which are uniformly distributed over the range kamp to -kamp. rand will thus generate uniform white noise with an R.M.S value of kamp / root 2. The remaining units produce band-limited noise: the kcps and xcps parameters permit the user to specify that new random numbers are to be generated at a rate less than the sampling or control frequencies. randi will produce straight-line interpolation between each new number and the next. Here is an example of the randi opcode. It uses the file randi.csd.
