Hi, 
this morning i rebuild Csound in Kubuntu ans wanted to upload an example for
the convolve opcode in CVS.
I got an error while making a convolve.csd.xml:

menno@muziek:~/CVS/manual/manual$ python csd2docbook.py -f convolve.csd
Traceback (most recent call last):
  File "csd2docbook.py", line 23, in 
    import csnd
  File "/usr/lib/python2.6/site-packages/csnd.py", line 25, in 
    _csnd = swig_import_helper()
  File "/usr/lib/python2.6/site-packages/csnd.py", line 17, in
swig_import_helper
    import _csnd
ImportError: No module named _csnd
menno@muziek:~/CVS/manual/manual$ csound -z
time resolution is 1000.000 ns
virtual_keyboard real time MIDI plugin for Csound
PortMIDI real time MIDI plugin for Csound
0dBFS level = 32768.0
Csound version 5.12 beta (double samples) Nov 29 2010
libsndfile-1.0.21
rtmidi: PortMIDI module enabled
RAWWAVE_PATH: /usr/local/share/csound/rawwaves/
1645 opcodes

On a previous built the command line "python csd2docbook.py -f convolve.csd"
worked. 
Has something changed in csnd.py or am i making a mistake?

thank you,
menno

Hi,

Did you remember to set PYTHONPATH?

Hi Andres

no, it worked yesterday before the rebuild of Csound i did today.
This is my PYTHONPATH:
PYTHONPATH=/usr/lib/python2.6/site-packages
??
There must be something else that is wrong.
Ant ideas?

Thanks for the insight. Then maybe it's because the interfaces are not
being built?

There was no lib_csnd.so in my system.

This morning i rebuild and installed Csound again and _csnd.so was actually
created. And "python csd2docbook.py -f convolve.csd" works now.
I am puzzled what went wrong. Probably an error on my behalf. I used less
arguments for scons this time but i do not know if it has anything to do
with this _csnd.so missing issue. Next time when i update Csound i will
investigate this further .

Thanks both for your time.
greetings,
menno

I've just made a small VST-plugin that picks up a csd-file in the same folder as the dll itself and applies it as an effect. CSound input channels declared at creation time (typically using chn_k) will be picked up as parameters.

This is of course very similar to CsoundVST and I have to admit that I've stolen some snippets of code from that project. That's why I believe that there is a bug in the CsoundVST::process(...) method. The call to performKsmpms(true) is at the wrong place in the loop. It should be at the very end. Today the code says:

for(VstInt32 hostFrameI = 0; hostFrameI < hostFrameN; hostFrameI++)
{
  for(channelI = 0; channelI < channelN; channelI++)
  {
    csoundInput[csoundFrameI *...] =  ...
  }
  if(csoundFrameI == 0)
  {
    performKsmps(true);
  }
  for(channelI = 0; channelI < channelN; channelI++)
  {
    hostOutput[channelI][hostFrameI] +=  csoundOutput[csoundFrameI *...;
  }
  csoundFrameI++;
  if(csoundFrameI > csoundLastFrame)
  {
    csoundFrameI = 0;
  }
}

The problem here is that the first sample of the input buffer is out of synch with the remaining. For instance with "ksmps=5" a correct input buffer should have the following sample numbers [0 1 2 3 4], but instead it contains [5 1 2 3 4]. This is very noticeable with relatively small ksmps (e.g ksmps=10). The correct version should be something like:

for(VstInt32 hostFrameI = 0; hostFrameI < hostFrameN; hostFrameI++)
{
  for(channelI = 0; channelI < channelN; channelI++)
  {
    csoundInput[...] =  ...
  }
  for(channelI = 0; channelI < channelN; channelI++)
  {
    hostOutput[channelI][hostFrameI] +=  csoundOutput[...;
  }
  csoundFrameI++;
  if(csoundFrameI > csoundLastFrame)
  {
    csoundFrameI = 0;
    performKsmps(true);
  }
}

It is sort of a mystery that this hasn't been noticed before, so maybe there is something that I've overlooked?

Best regards,
Sigurd

Thanks for your report. I will definitely check this out.

By the way, I have thought about making another version of CsoundVST
that does not have a GUI, just a dialog that asks for and remembers
the path to a CSD file that would be edited by an external editor. As
you probably know, you can use an instrument as an effect or an effect
as an instrument, so only one mode is actually required.

Mike

I posted some code to this list about a year ago that implements a
Csound VST bridge so to speak, search for csVST. It uses only the
native host GUI and is relatively easy to use. It's also borrows
heavily on Mike previous work with Csound VST!

Sounds very interesting. But without a GUI, will you also be without parameters that could be picked up by the VST host for automation?

My intention was to keep this as plug and play as possible for my students: No programming (except for CSound, of course) and no custom CSound statements. Just write a *.csd file with ins/inch and outs statements. Declare parameters with chn_k (using the various options to tune the presentation). Drop the csd file in the same folder as the dll and it will be picked up. Declared parameters are available for GUI and for host automation.

I use Juce as a framework and auto-generate a simple GUI with buttons and sliders. It should work for AU and RTAS plugins with small modifications, but I haven't tried anything but VST yet. Parameters can be controlled through MIDI, but I haven't decided on a strategy for triggering notes/instruments, so currently it works as effect only.

It would be possible to enable parameters using the built in sliders.
You either could create a fixed number of parameters that the CSD
would be free to ignore, or to use and interpret as seen fit, or else
you could parse the csd and create sliders for global variables,
perhaps with a naming convention.

BTW, I'd also like to use VeSTige and get away from dependency on Steinberg.

Mike

No GUI apart from the native sliders that are provided by the host I
meant to say. I'm putting the finishing touches on a Juce/Csound
plugin development framework. The good news is it's working very well
VST/AU and Linux VST. The bad news is I got a notion to add some extra
functionality to it before releasing it so it has set back my release
date by a few weeks.

Very interesting news. Please keep us informed about the release, I'd 
love to test it.

Extra functionality is a killer for development plans ;-)

BTW: I found some references to csVST and zipped code in a posting from two years ago (time flies, I guess), but the link to the attachment was dead. It would be great to have a look at what you've done, so if you find the time please repost.

No GUI apart from the native sliders that are provided by the host I

I'll have to dig it out from my other computer but will try to t it to
you shortly. One thing which I did, which I won't be doing again is
provide a tool for embedding the csd file into the binary dll.
Finally, it must be said that the code I posted was started by a
student of mine so I can't take all the credit!

Will do. I've even given up messing with synths for the afternoon to
do some work on it :( such tough decisions.....

Mike, 

Out of curiosity: Is there a good reason why you suggest parsing for global variables instead of using control channels (chn_k) and the csoundListChannels() method? It seems so much simpler, and you could exploit the range and type of the declared control channels to set slider properties (range, integer, float, exponential, etc.). It works nicely for me. 

Sigurd

Subject: Re: [Cs-dev] Bug in CSoundVST?

It would be possible to enable parameters using the built in sliders.
You either could create a fixed number of parameters that the CSD
would be free to ignore, or to use and interpret as seen fit, or else
you could parse the csd and create sliders for global variables,
perhaps with a naming convention.

BTW, I'd also like to use VeSTige and get away from dependency on Steinberg.

Regards,
Mike
