Hi,

I'm suffering to much to have the csounQt pipe_synth example working on 
Linux with csound6-git.

I come to the test csd showing one of the problems.

If setksmps to 1 (in the REVERB opcode) everything is ok

If set to an other value (less or equal to 512) csound is giving funny 
outputs.
(On test2.jpg channel 1 is ok and channel 2 not. )

An other funny thing, with setksmps not equal to 1 , I have a seg fault 
if I remove *1.0 in outs line !

Please somebody can told me what is wrong with this csd to work with 
csound6.

Regards,
René

Hi Rene,

I think this was a bug in UDOs that has been fixed by Victor in git. Try getting the most recent csound from git and let us know if this has been fixed.

Cheers,
Andrés

Hi Rene,

This sounds like a bug introduced in CS6.  Could you file a bug in the
tracker for this?

Thanks!
steven
