Hello All,
my csd using chnexport opcode was working before, but not today with 
Csound6 build yesterday.
If i comment out the line with chnexport opcode the csd work.

Has something changed?

Thanks,
ciao,
francesco.

Hi Franceso,

I've tried this on OSX and got pretty much no audio with both CS5 and
CS6.  I assume you're using this within a host application of some
sort?  If so, what platform are you running this on?

Thanks,
steven

Hello Steven,
yes, You are right i'm controlling this csd from a Lua script,
in Ubuntustudio 12.04 32 bit.
No audio, i guess, because all k parameter for chebyshev (gk1 to gk4)
are set to 0.
It works with Csound5, not with Csound6, although i seem to remember 
that was working a few days ago (not sure now).
Commenting chnexport lines, it works.

Thank You,
ciao,
francesco.

Hi Francesco,

Could you attach a lua script to test this csd with?

Thanks!

Yes, but i will need to adapt it. Give me some time and i will post here.
Anyway if i move gaL and gaR init after the chnexport it works.
i.e.

endin

aL = al*ilev + gaL*(1-ilev)
aR = ar*ilev + gaR*(1-ilev)

gaL = 0
gaR = 0
endin

Hi Francesco,

I think I've found the bug and fixed it.  Took a while to get setup as
I had to get the Lua interface built and figure out some gdb issues
with pthread.  The project runs for me now, but I did the debugging in
a Virtual Machine (Debian 7.1 amd64) so it was going really slow for
audio output.  I can't test as the Lua interface doesn't build on OSX.
 Could you retest with the latest from GIT?

Thanks!
steven
