Joke?
Are you saying the basslines in for example Lost Theory and the first half of All Channels Open aren't bouncy, or that they only use one note? Same goes for the bassline in for example the start of The Poisonous Square or in parts of Fnatt... and I have never ever heard anything like the bass in the end of the last song. And Derango always use many different basslines per song, adding a good deal of variation. Sure, many times it's only one note - because it fits very well for this kind of music (I mean a lot of darkpsy uses the same one note pattern throughout whole songs, and that works), but you can't say that their basslines are always the same, nor boring imo
