Ok, we made lots of progress and now we have tests versions for macOS and Windows (32 and 64 bits).
Here's for everyone to test if all the links for dynamic libraries are working :) https://github.com/porres/pd-fluidsynth/releases/tag/test-1
we still need to sort this for linux, write a better readme with build instructions and reorganize things so then we can upload it to deken as a final/oficial release.
thanks for everyone who helped. Alex
