i only tried xphrase real quick. But i have Absynth 2. It would work pretty well for techno style stuff. Also Linplug Albino 2, and Vanguard would work well for that style. Actually Absynth has a few sounds that would work, but it is mostly more weird creepy sounds that would work in eerie movie soundtracks. Its not very pleasant, so i dont use it that much. Albino 2 or Vanguard would be better for what you want in my opinion.
