Hello,

It seems again a problem with the resolution of the phase increment of oscili. On a Mac-Intel (small), using csound single precision, I get a small click at the end with your example. If I replace oscili with poscil, the click disappears. I do not have the double version on this machine, but you can try this hack to see if it works with yours.

Best,

Marco

Thanks for testing Victor. In that case it sounds like a problem with the double version (or at least on OSX). 

Just the thing I didn't want to hear!! :-(

Thanks

I ran your CSD here and got no noticeable click at the end (I am using
floats version).

Subject: [Csnd] problem with envelope (Please help a very frustrated composer!!)

Hello

Please tell me I've lost my mind and am doing something completely stupid!
I've managed to narrow the problem down to one sine-tone after hours of
striping my orchestra.

For some reason when I run the attached csd I get a click right at the end.
However, increasing ksmps from 1 to 16 gets rid of the glitch. This is
strange as the envelope is k-rate and should only get better with higher
control rate.

I'm on csound64....

Any suggestions will save me hours of head-banging!

All the best
Peiman
