Hello,

I just wanted to share a piece I made this summer using Csound for
processing semi-binarual sondscapes. The piece’s title is “What is
it?” and it’s available here (the last one):

http://ea.hcenteno.net/listen.html

Also I made a 8 channel version spatialized using the vbap opcode
(tweaked for realtime change of azimuth). On the concert day it was
live spatialized through 12 channels using an excellent patch on
Max/Msp called Spit and a hand held motion sensor (accelerometer).
Next month I’ll be trying to implement a Csound based system to
controll vbap using a Wiimote.

Cheers!

Hector

Hi,

After reading Victor’s tutorial:
http://csounds.com/articles/Extensions_to_Csound.pdf
and building the example under 3.3.2 “plugin function tables”,
csound tells me that the GEN number 44 is unknown (see test.csd below).
Is there a way of getting feedback when a GEN plugin was loaded and
which number it has?
The tutorial says that there are 43 internal GEN routines and GEN
plugins are numbered according to their loading order but according to
the manual the highest GEN number is 52. I tried out 53 but that didn’t
work either.
I am sure that the new shared library is in the right place.

C code and test.csd as follows:

///////////////// GEN plugin ///////////////////////////
#define USE_DOUBLE 1
#include “csdl.h”
#include <math.h>
void tanhtable(CSOUND *csound, FUNC *ftp, FGDATA *ff)
{
/* the function table */
MYFLT* fp = ftp->ftable;
/* f-statement p5, the range */
MYFLT range = ff->e.p[5];
/* step is range/tablesize */
double step = (double)
range/(ff->e.p[3]);
int i;
double x;
/* table-filling loop */
for(i=0, x=FL(0.0); i<ff->e.p[3];
i++,x+=step)
*fp++ = (MYFLT)tanh(x);
}

static NGFENS localfgens[] = {
{ “tanh”, (void(*)(void))tanhtable},
{ NULL, NULL}
};

#define S sizeof
static OENTRY *localops = NULL;

Hi all,

I have just published a new piece called “Aurora (for Kraig Grady)”. It’s a short one, just over 3 minutes.  It was written in Csound using blue and Scala.  All source code is available for download, along with OGG and MP3 renderings, at

http://mysterybear.net/article/24/aurora-for-kraig-grady

As always, comments are welcome.
