I installed all the mentioned externals, except for ceammc, which PlugData could not find.

Now the right side with local files and random function works, but I got a list of errors.
(btw, copy/paste does not work at all from Plugdata on my system. I used an app called NormCap, which can read text from images.)

plugdata v0.9.2 Based on Pd-0.55.2 Libraries:
ELSE v1.0-re13 cyclone v0.9-2
Gem v0.94
heavylib v0.4
pdiua 0.12.23 (lua 5.4)
