Thanks, I forgot about dssi~. I'll give it a go.

What's the story behind the "postlude" edition?!

thanks Rua HM.

Hi Rua,

Have you tried using dssi~? It can host LADSPA and DSSI plugins as well as multiple instances of the same plugin. It's available in svn or (for ease of use) in the Pd-extended 'postlude' edition:

Hi - I am trying to use LADSPA plugins within Pd and am having a tough time... attached is an example patch I am trying to get to work. It's simply a mono noise source through a comb filter. The particular plugin is the SWH comb filter (http://plugin.org.uk/ladspa-swh/docs/ladspa-swh.html). The problem is I get no sound out of the output of plugin~.

I am on Mac OS X 10.5.7 using 0.40.3-extended. (I have downloaded 0.41.4 but am having some crash-on-launch problem with that so am sticking with 0.40.3 for now).

I have copied all my LADSPA plugins to the appropriate place, and they are found and instantiated correctly by plugin~, info displays correct info etc.

Can someone give me some tips on how to use LADSPA plugins in Pd on Mac OS X, or email me an example patch?

Note that the case in particular that I care about is using Pd to host sidechain compression (and other nonlinear routing things) - I initially tried getting SWH SC3 (great sidechain compression!) to work in Pd, and audio was passing through, but I couldn't produce any compression, it seemed as though I had the parameter inputs set up incorrectly. So if anyone can give me an example of how to do this I'd _really_ appreciate it.

Any tips, info, or clues would be greatly appreciated :)

thanks Rua HM.

It's a version of extended that I use for my own personal work. It's
extended with some extra stuff added in including csoundapi~, dssi~

• some DSSI plugins, aubio, libxtract etc. My domain used be

postlude.co.uk hence 'postlude', but it could just as well be the
'jamiebullock' edition ;-)

I fully intend to start merging stuff from postlude into extended
proper, it's just a question of time and priorities.

An easy next step would be to make that stuff into a libdir, then
people can just drop it into the user externals folder to install it.
I guess the hard part is including the dependent libs on Mac OS X and
Windows. On Windows, you can just include the DLL in the same folder,
on Mac OS X, you have to do a bit more since dylibs use the complete
path.

You have to tell the pd object to link to the dylibs in the same
folder like this:

install_name_tool -change /sw/lib/libgavl.1.dylib libgavl.1.dylib
readanysf~.pd_darwin

And you have to tell the dylib itself that it doesn't have a path:

install_name_tool -id libgavl.1.dylib libgavl.1.dylib

.hc

best,

Jamie
