I just started using pd today and I'm a bit confused about the externals. I'm trying to make a simple convolver to use as a cab sim, and the easiest way I imagine doing that is with the FIR~ object. However I can't create the FIR~ object, so I went to check where I think it should be installed (/usr/lib/pd/extra/iemlib/) and there is no FIR~.pd file. There is however a FIR~-help.pd file (with a broken FIR~ object inside).
I tried reinstalling puredata, and iemlib, but nothing changes.
So, am I correct in thinking there should be a FIR~.pd file in /usr/lib/pd/extra/iemlib/? If so, where can I download this file?
