<br>
I'm stuck with a problem trying to sprout process with Csound. I'm<br>
trying to do something more complex with a piece I'm working on, but<br>
managed to boil down the problem I'm having by using the Csound Scheme<br>
example. If you take a look at that example, you'll see a function<br>
called ransco:<br>
<br>
(define (ransco len rhy lb ub amp)<br>
(let ((dur (* rhy 2)))<br>
(process repeat len<br>
for t = (elapsed #t) ; get true score time<br>
for k = lb then (between lb ub)<br>
do<br>
(cs:i 1 t dur k amp)<br>
(wait rhy))))<br>
<br>
<br>
A bit further down in the example, there's some instruction on sprout<br>
this bit multiple time, using :write #f to 'collect' the events<br>
generated into one score:<br>
<br>
<br>
; This will generate a score without writing an audio file. execute<br>
; the expression several times and use the Audio>Csound>Export... item<br>
; to export all the score data in various formats<br>
<br>
(sprout (ransco 10 .2 60 72 1000) "test.sco" :write #f)<br>
<br>
I was assuming I'd be able to do this same thing from a process, but<br>
I'm getting an error that Grace is unable to get a file handle to<br>
"test.sco". Here's the function:<br>
<br>
(define (f1)<br>
(process repeat 3<br>
do<br>
(sprout (ransco 10 .2 60 72 1000) "test.sco" :write #f)<br>
(wait 1)))<br>
<br>
...and I try to execute it like so:<br>
(sprout (f1))<br>
<br>
<br>
Is this one of those 'not yet implemented' features, or am I missing<br>
something? Any help is very much appreciated - thanks! Complete<br>
