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

Thanks!

For now I'll go back to the float version to keep busy at the weekend! I
should say that the click remains when I render to disk - see attached png (
http://www.nabble.com/file/p19580977/Picture%2B1.png Picture+1.png I've
increased the amplitude to make it more visible).

There is one issue with the frameworks I should mention. If csound64 is
installed in framewoks64 as opposed to frameworks then csound~ max/msp
external cannot run using the double version. The shell looks for framewoks/
and gives an error message when trying to run csound within max.

I guess this could also be fixed by releasing two versions of csound~. I'll
have to email the creator and ask if that is possible.

Best
Peiman
