Rich is right about the 140, start there and don't stray off more than 4 bpm. The funny thing about dubstep is it's ACTUALLY at 70 bpm and you write everything in half time. So assume your drum machine (redrum, ableton, etc) has a 16 beat loop in it with 4 beats per measure. On your track it has a kick and snare every measure making it fast. Imagine slowing it down half as fast. Put a kick on the first beat and then wait two measures, put a snare on the first beat of the 3rd measure. So instead of
Kick - - - Snare - - - Kick - - - Snare - - -
Do
Kick - - - - - - - Snare - - - - - - -
Repeat ;-) I hope this helps, I've spent alot of time deciphering why it's so hard to make such simple music, such is dubstep.
on believe the hype - short - hoping for guidance by phatcontroller
Kick - - - Snare - - - Kick - - - Snare - - -

Kick - - - - - - - Snare - - - - - - -
