just to jump on and slightly hijack the thread...808/909's are top bill.............from what i beleive, just incorperate the the bassline in conjunction into the percussion....as a rule.........never bring in over sampled parts to a tune unless the percussion/breaks/bass is flowing..............imo thats the heart to a tune................im sure you already know this, but it is a golden must
best of luck mate, and keep us posted on the progression
