Okay, upon further looking. What seems to be happening is that the executables for whysynth or hexter no longer work, BUT I can start the synths at the command prompt by calling them through DSSI as: /usr/local/bin/jack-dssi-host whysynth.so or /usr/local/bin/jack-dssi-host hexter.so So the synths in fact DO work, but for a reason I can't understand, due to my lack of knowledge I would guess, I can't call them with the executable files that were put in the /usr/bin folder, therefore none of their shorcuts work.
