Quoting Hector Centeno hcengar@gmail.com:

Also, I was wondering if anyone has a link to a manual page for the old [matrix] and [matrix~] so I can understand whats going on and see how to replace them with the newer ones.

the problem is, that both [matrix~] from iemmatrix and from cyclone
are incompatible; so which documentation do you want?

the doc for iemmatrix's [mtx_*~] should give you some clues on how the
object is used (even in the old incarnation of [matrix~]. basically,
the matrix now goes into the 1st inlet instead of the second-last one
and it has to be transposed. the old version used a notation of out^ = in^ * A while the new version uses out^ = B * in^

(which implies that B=A')

i do not know of anz issues with the [matrix] object nor of any
incompatibilities. i do not conisider it deprecated.

Hello Kevin,

Thank you for your response. Does that mean I have to change the patch ( vbapdemo.pd) to substitute the [matrix] and [matrix~] by [mtx_mu] and [mtx_mu~]? Do they work the same or that means I would have to do further changes?

Thanks!

Hi Hector,

As far as I remember, the correct one to use is [mtx_mul] and [mtx_mul~]; as IOhannes told me, [matrix] & etc is deprecated if I remember correctly. The correct ones are from the excellent iemmatrix library.

I think the vbap directory is the more recent one which should be Ville Pulkki's work. Have a look at the documentation in there.

Hope this helps, Kevin

Hi,

I'm trying to get vbap working using Linux Fedora 7/Planet CCRMA. I'm

the Planet's packages which are version 0.39.2. First I found vbap in

/usr/lib/pd/extra/vbap /usr/lib/pd/extra/ggee

What is the difference? So I tried with the vbap directory. When trying to load the demo I

Does anyone know which ones are the right ones to use? I managed to

cyclone

I did some work in the vbap directory a couple of months ago to include the rvbap object, which also has a distance control using reverbs etc. The help file for rvbap uses the new names for the matrix objects in iemmatrix. You can use these as starting point for working with vbap as well.

Or just use rvbap directly. It's not that much more demanding cpu-wise. You can find it all in the CVS at Sourceforge in the vbap directory and on Fedora, building the objects is just one "make" away. I don't remember, if there also is a "make install" target, but you can just copy over the *.pd_linux files to your externals directory (like "extra") and the *-help.pd files to 5.reference manually.
