That makes sense, thanks! Though I'm having a hell of a time getting pd to load the hid external on the rpi. I've put the folder in /usr/lib/pd/extra and tried using the declare object but it just won't load...

i have spent entire day on this shit
here is what you need to add to PD command line,in my example was ELSE lib
-path /home/pi/Documents/Pd/externals/ -lib else
