I agree with tweak, they don't exist. The trend nowadays is for artists to put up sample/patch packs up for sale on Beatport, Loopmasters etc. Even then the virus doesn't usually get a look in. The patches are mostly for Massive or Sylenth. There are still 'sound designers' making patches for the virus but most of them are just re-hashes of older stuff or shit you could make yourself easily if you learn the synth.
Having said that there are ton's of freebie soundbanks available from access's web site which could be used in any techno track...hey it's not exactly the highest musical art form ; )
BTW EDM stands for electronic dance music...thats what techno is, music made with electronic instruments that you dance too, or mong out too if you have taken too much gear
