When reading about 'Scanned synthesis' in https://en.wikipedia.org/wiki/Scanned_synthesis I see about the [pdp_scan~] external from 'pdp', but I can't use it... I can still try extended in my machine and it didn't really work back then, I get

Applications/Pd-extended.app/Contents/Resources/extra/pdp/pdp.pd_darwin, 10): Library not loaded: /usr/X11R6/lib/libX11.6.dylib
  Referenced from: /Applications/Pd-extended.app/Contents/Resources/extra/pdp/pdp.pd_darwin
  Reason: image not found
pdp: can't load library

Purr Data can't load it either.

The 'pdp' version in deken (0-0extended) doesn't work either and all print the same error.

I wanted to check this object out, does anybody know where the source lives and if we can try and compile it?

cheers
