How much bass is too much bass?!?
you need to have a good key to begin with, there are certain keys that just arent going to be any good in drum and bass when it comes to sub bass, including C, things around f, f#, g, g#,a, b that kinda shit will sit really well in the sub bass department and kick you in the face more.
check your tunes in a spectrum analyzer and see how loud the sub bass is compared to the kick drum, get them the same level is a nice little rule i guess, but not saying the bass cant be louder, you just want them similar in volume. look at professional songs and note down the levels of things.
May be a late reply but i find the best sub bass comes from a malstrolm (however you spell it)may have been posted but take a malstrolm flip it round and insert a scream 4 set on tape route the outputs of ocisslaters A and B into inputs of scream then back into filters on malstrolm get me?? then set your octave and as said copy and paste notes
instant fat sub
hope that helped
one thing i do to make the flat sub notes sound on the same level as the other notes, is after the eq and compressor chains, i stick in a Maximizer, select limiter and 4ms look ahead, boost the signal so ALL the notes hit the 2 indicators into the red zone (over). then hit the softclip button (the signal will then hit 0db and will not clip).. adjust the softclip dial to your liking and... BABOOOM! fat sub
