| Hello, for some strange reason I am getting a horrible pop in the left channel every time I use the csd bellow (basically the diskgrain opcode. Regardless of what soundfile I use... I believe this instrument was working faultlessly in the past.
I am on osx using the latest csound float (installed with the installer). Any ideas are appreciated. Thanks in advance Peiman ; ; "" ; by peiman khosravi ; ; ; ; Generated by blue 0.125.0 (http://csounds.com/stevenyi/blue/index.html)

...but there is something wrong with diskgrain.

| Thanks Victor, That was indeed a miss type due to incomplete copy and pasting from blue. But changing it doesn't seem to make any difference to the distortion at the beginning of the performance.
Try this score event (changing the soundfile path of course): i2 0.0 11.0220384598 -14.872631 "/Volumes/Peiman120GB/sounds/gongWarp/gong rub.wav" 0.8634113 0 8 0.108215176 2.8460302 577.25574

The fact is that using CVS sources at the moment,
there seems to be something
very wrong with diskgrain and syncgrain too. I
can't seem to understand what is
wrong (feels just like some silly mistake). It's
way too slow and producing the wrong
output. I will see if I can find why. Nothing much
has changed in the code, so
that is why it is strange.
There was a problem with diskgrain but I have a
feeling it was sorted before the last
release.

I found the bug in CVS. Will discuss a fix with
John.
