Hi all. I'm a csound newbie (got it two days ago) but
I have plenty 
of programming experience (both computers and synths).

Is there any way to repeat a group of i-statements
within a section? 
I know there's the r-statement but that doesn't work
for what I want 
to do. 

Let me give you an example. Suppose there is a
"L-statement" (for 
looping) that works just like the r-statement but
within a section. 
Thus something like this:

;
------------------------------------------------------------
i1 0 0.5  ; this is a kick drum playing on beats 1 and
3
i1 2 0.5

L8 HOffset   ; loop statement: repeat 8 times with
counter HOffset
i2 [($HOffset. - 1) * 0.5] 0.25  ; closed hi-hat every
eight note
L0           ; this may be used to close the loop

i3 1 0.5  ; this is a snare playing on beats 2 and 4
i3 3 0.5
s         ; end of section
;
-------------------------------------------------------------


would be translated into this:

;
------------------------------------------------------------
i1 0 0.5
i1 2 0.5

i2 0.0 0.25
i2 0.5 0.25
i2 1.0 0.25
i2 1.5 0.25
i2 2.0 0.25
i2 2.5 0.25
i2 3.0 0.25
i2 3.5 0.25

i3 1 0.5  
i3 3 0.5
s         
;
-------------------------------------------------------------


Is there any way to do something like that? I have
checked and 
rechecked the manual but can't find anything similar.
The r-statement 
wouldn't work because it resets the timer.

Macros could be used but they are not really the
solution. The 
section in the previous example is only 1-bar long,
but what if I 
want a 16-bar section with hi-hats every 16th note? Do
I have to type 
(or copy&paste) 256 statements ?

This is probably very easy to accomplish with a
program as advanced 
as CSound, I just can't find it on the
manuals/tutorials.

Thanks in advance.

Thanks, Steven. I'll give it a try.

I saw those utilities (blue, cecilia, etc.) but I
thought I would first get the hang of the standard
CSound before I tried the "extras".

Thanks, Aidan. I saw the reinit opcode in the manual
but I thought the solution would be at score-level.

I'll try your approach and see what comes out.

Thanks again.
