a lot of the big names in future house like curbi and pep & rash just take your typical big house synths and melodies and layer a bass under the melody. standard doop doop drop with a bass on each note, rather than the 808 style festival kick. throw a low pass filter over the top line and get rid of everything above 10k or whatever so you can copy and paste a vengeance future house percussion top sample and you're rich.
