John,

I have tried several times to post this to the list
(csound@maths.ex.ac.uk) but, for some reason, my message has yet to
"appear". Hence, I thought I might send this along to you as I know you
would be interested in this posting and, if you desire, might pass it
along to the group. Here is what I have been trying to send:

The following simple orc and sco files produce a 24-second soundfile
(4 seconds of sound followed by 20 seconds of silence) using the latest
version of Csound, (ver. 3.485). However, all previous versions of Csound
caused the following orc and sco files to produce only a 4-second
soundfile. Here is the orc and sco:

;ORC
sr = 44100  ; sample rate
kr = 882    ; control rate
ksmps = 50  ; number of samples in control period (sr/kr)
nchnls = 2  ; number of channels (mono)
           

instr 1
a1     soundin "left.wav" ; (wave file 2 seconds in duration)
       outs    a1 * 1, a1 * 0
endin

instr 2
a2     soundin "right.wav" (wave file 2 seconds in duration)
       outs    a2 * 0, a2 * 1
endin

;SCO
i1  0  2
i2  2  2
e

Why does Csound 3.485 now add 20 seconds of silence at the end for the
above orc and sco files whereas all previous versions did not?
