I am new to Pd. I'm moving from the max. Someone give me directions to install the externals.

Do you get any messages at startup saying libraries couldn't load? Are you using the same version of Pd (extended, I assume)?

No I don't get any messages at startup,,,, and yes I'm using the latest pd-extended - thanks for the reply

Are you using the release candidate of Pd-extended? Do you get messages saying "libdir_loader: added 'blah blah' to global objectclass path"? I ask because I think the plan for future versions of Pd-extended is to not have a default set of startup libraries. I haven't tried the new release candidate, so I don't know if that idea has been implemented yet. But if you don't get the above message, you might need to add the libraries to your startup path.

Ah actually yes I did get a message at startup which is -
[import] $Revision: 1.2 $
[import] is still in development, the interface could change!
compiled against Pd version 0.41.4
This may be the problem? Adding libraries seems very convoluted....

Thanks for your help!

The [import] message isn't a problem. But having no "libdir" messages is. Do you have anything listed in the Preferences->Startup...?

Thnaks for answer. I've installed pd-extended 0.41. My problem is with the object matrix and ambisonics library.
Sorry for my english. And Thanks!

No I have no messages in Preferences->Startup...

That might be the problem. First, check <home folder>/Library/Preferences and delete org.puredata.pd.list, if it exists. Then reinstall Pd-extended. If that doesn't fix it, you might need to set the Startup... libraries manually. Here's what I believe are the default libraries:

libdir
Gem
cyclone
zexy
creb
cxc
iemlib
list-abs
mapping
markex
maxlib
memento
mjlib
motex
oscx
pddp
pdogg
pixeltango
pmpd
rradical
sigpack
smlib
toxy
unauthorized
vbap
pan
freeverb
hcs
jmmmp
ext13
ggee
iem_anything
flib
ekext
flatspace
pdp
pidip

Note: it's very important that libdir be the first one! Just add all those and you might be set. Hopefully you don't have to add anything to Path..., as it's kind of a pain in the ass to do it in OSX.

@MZ: go to Preferences->Startup... and add iemmatrix and iem_ambi to the list.

Thank you so much! Deleting org.puredata.pd.list fixed the problem! I'm very grateful for your help and am also very grateful that I didn't have to set the startup libraries manually... Thanks again!
