rite now this is a very interesting question

i went for a shitty college course and i had a engeneer showin me cubase and reason, basically they thort how i made tracks was amazingly weird as i apply fx as im goin though, what she said was apply teh fx after the tune was made, which i thort was strange. i couldnt make a tune iwthout a perc and bass first

this bein the foundatyion set sthe groove and gives teh feel to the tune, from that i get the inspiration for the other sounds i will use in my tune

so for me has to be perc + bass
