The r score command needs TWO arguments. The first is a count, and
the second is the name of a macro which takes the value of the
iteration. Without the macro name it wikk fail. OK, there ought to
be better error checking. Will look at it.

There does seem to be some confusions in the whole area of the random
number generators in Csound.
First, the rand, randh and randi opcodes have a simple (trivial) small
cycle pseudo randon number generator. They are not affected by the
seed opcode, but only the optional seed argumrnt. Each opcode is
independednt, and follows the same sequence.
The noise generators on the other hand use the ANSI C rand function,
and all share the SAME sequence, which is reasonably long cycled (30
bit typically).
It would help if people where clear as to which one they mean in these
discussions.

I have found the rand,randh and randi opcodes very annoying when used for
a-rate signals, because in my humble opinion they don't have a "reasonably
long"
cycle as I can always hear the cyclic repetition ! It sounds like a looped
sample,
and not like a stream. However those other, non-uniform random generators
like gauss, weibull etc are very well suited for a seamless stream !
What is the technical difference between the cyclic rand and the
non-uniform generators ??

I have found the rand,randh and randi opcodes very annoying when used for
a-rate signals, because in my humble opinion they don't have a "reasonably
long"
cycle as I can always hear the cyclic repetition ! It sounds like a looped
sample,
and not like a stream. However those other, non-uniform random generators
like gauss, weibull etc are very well suited for a seamless stream !
What is the technical difference between the cyclic rand and the
non-uniform generators ??

I have found the rand,randh and randi opcodes very annoying when used for
a-rate signals, because in my humble opinion they don't have a "reasonably
long"
cycle as I can always hear the cyclic repetition ! It sounds like a looped
sample,
and not like a stream. However those other, non-uniform random generators
like gauss, weibull etc are very well suited for a seamless stream !
What is the technical difference between the cyclic rand and the
non-uniform generators ??

I have found the rand,randh and randi opcodes very annoying when used for
a-rate signals, because in my humble opinion they don't have a "reasonably
long"
cycle as I can always hear the cyclic repetition ! It sounds like a looped
sample,
and not like a stream. However those other, non-uniform random generators
like gauss, weibull etc are very well suited for a seamless stream !
What is the technical difference between the cyclic rand and the
non-uniform generators ??

Could anyone recommend a simple way to generate random +1's and -1's
(whole #'s - nothing in between and no zeros)? Maybe there's a simple
formula I could use with krnd without using if - then statements?

I have found the rand,randh and randi opcodes very annoying when used for
a-rate signals, because in my humble opinion they don't have a "reasonably
long"
cycle as I can always hear the cyclic repetition ! It sounds like a looped
sample,
and not like a stream. However those other, non-uniform random generators
like gauss, weibull etc are very well suited for a seamless stream !
What is the technical difference between the cyclic rand and the
non-uniform generators ??

Could anyone recommend a simple way to generate random +1's and -1's
(whole #'s - nothing in between and no zeros)? Maybe there's a simple
formula I could use with krnd without using if - then statements?
Thanks as always

Could anyone recommend a simple way to generate random +1's and -1's
(whole #'s - nothing in between and no zeros)? Maybe there's a simple
formula I could use with krnd without using if - then statements?
Thanks as always

I have found the rand,randh and randi opcodes very annoying when used for
a-rate signals, because in my humble opinion they don't have a "reasonably
long"
cycle as I can always hear the cyclic repetition ! It sounds like a looped
sample,
and not like a stream. However those other, non-uniform random generators
like gauss, weibull etc are very well suited for a seamless stream !
What is the technical difference between the cyclic rand and the
non-uniform generators ??

Could anyone recommend a simple way to generate random +1's and -1's
(whole #'s - nothing in between and no zeros)? Maybe there's a simple
formula I could use with krnd without using if - then statements?
Thanks as always

I have found the rand,randh and randi opcodes very annoying when used for
a-rate signals, because in my humble opinion they don't have a "reasonably
long"
cycle as I can always hear the cyclic repetition ! It sounds like a looped
sample,
and not like a stream. However those other, non-uniform random generators
like gauss, weibull etc are very well suited for a seamless stream !
What is the technical difference between the cyclic rand and the
non-uniform generators ??

I have found the rand,randh and randi opcodes very annoying when used for
a-rate signals, because in my humble opinion they don't have a "reasonably
long"
cycle as I can always hear the cyclic repetition ! It sounds like a looped
sample,
and not like a stream. However those other, non-uniform random generators
like gauss, weibull etc are very well suited for a seamless stream !
What is the technical difference between the cyclic rand and the
non-uniform generators ??

Could anyone recommend a simple way to generate random +1's and -1's
(whole #'s - nothing in between and no zeros)? Maybe there's a simple
formula I could use with krnd without using if - then statements?
Thanks as always

Could anyone recommend a simple way to generate random +1's and -1's
(whole #'s - nothing in between and no zeros)? Maybe there's a simple
formula I could use with krnd without using if - then statements?
Thanks as always

I have found the rand,randh and randi opcodes very annoying when used for
a-rate signals, because in my humble opinion they don't have a "reasonably
long"
cycle as I can always hear the cyclic repetition ! It sounds like a looped
sample,
and not like a stream. However those other, non-uniform random generators
like gauss, weibull etc are very well suited for a seamless stream !
What is the technical difference between the cyclic rand and the
non-uniform generators ??

Could anyone recommend a simple way to generate random +1's and -1's
(whole #'s - nothing in between and no zeros)? Maybe there's a simple
formula I could use with krnd without using if - then statements?
Thanks as always

Could anyone recommend a simple way to generate random +1's and -1's
(whole #'s - nothing in between and no zeros)? Maybe there's a simple
formula I could use with krnd without using if - then statements?
Thanks as always

k1 rand
k2 = 2*int(2*k1)-1

Erik forgot that rand goes from -1 to +1 instead of the usual 0 to 1.
Erik's been busy programming things other than Csound (such as multimode
heat transfer). Hey, I spent all of 3 minutes on it.

I have found the rand,randh and randi opcodes very annoying when used for
a-rate signals, because in my humble opinion they don't have a "reasonably
long"
cycle as I can always hear the cyclic repetition ! It sounds like a looped
sample,
and not like a stream. However those other, non-uniform random generators
like gauss, weibull etc are very well suited for a seamless stream !
What is the technical difference between the cyclic rand and the
non-uniform generators ??
