I dont believe in any such thing as a 'must have' sound set for 2 reasons, the first being, the sounds you want or need really depend on what kind of music you want to make with this instrument (thats assuming that some people DO actually use this synth to make music although not much of it on this forum...cmon lets hear some more tracks peeps!) The second reason is that if someone has created a patch then U2 can recreate it if you know enough about the synth...hey its not rocket science. Just my 2c
