Subject: [Csnd] realtime error CsoundAV

Hey all,

I am trying to compile some realtime examples under csoundAV .0432 and i get the following error:

 " rtevent:       T  0.000 TT  0.000 M:new alloc for instr 3:
error skipping unknown chunk in WAV file."

No wave files are used only .pvx files. Any ideas thanks again.

Hello

Having installed Csound 5.07 (d) and Python 2.5.1, most *.py files under 
/examples and /examples/py will not run. Some of them reported something 
about a missing wx module, so i looked around, installed the wxPython 
binaries and most *.py files still won't run (though the report 
different, more complicated errors now).

What am i missing?
Is there a "suggested" python version?
Something else?

Canonical Csound5 superseded CsoundAV, but it doesn't support video and
OpenGL realtime motion graphics yet.
A CsoundAV5 alpha version (based on on Canonical Csound5) has been
posted to the developers some time ago (I don't use CVS).

Some (little) changes to the core of Csound5 have been necessary to work
with OpenGL realtime motion graphics, so a simple opcode library
containing OpenGL opcodes is not sufficient. Unfortunately, I noticed
that the Portaudio code of Csound5 is not as responsive as the one of
CsoundAV for realtime control so far, at least on my WinXp computer.
Until now I 've not had the time to indagate and to adapt the portaudio
code of CsoundAV to CsoundAV5. So motion graphics is stuttering when
using audio AND graphics in CsoundAV5 alpha. But, if audio is
suppressed, graphic motion is quite smooth.

Gabriel,

you don't need to use the portaudio module. You could just write your
own module based on your older code. That's not difficult at all and it
might solve your problem.

Thanks Victor, I will indagate on it in the future. Unfortunately, at 
present time I'm very busy in non-Csound things...

Best
