Personally I've found a formula that works quite nicely and am pretty happy with it, I thought I'd share it, as havn't shared much of my own ideas yet, just learning from others. I start with tracks ready for kicks, snares, ghost hits, and breaks/percussion, for which I highly recommend using rex files in a sampler- in my case the exs24. I process all of these tracks purely with subtractive EQing, and transient shaping I then start routing. I do this by changing the output of the kick tracks to the input of my kick bus, the snares to a snare bus, the ghost hits to a ghost bus, the breaks and percussion to a percussion bus. With all of these groups, I will separately process, using further eq and compressors etc. I then change the outputs of all of these buses to route them all to my DRUMS bus. Of course I apply some processing to the drums bus too, filtering eqing and compression etc etc. I then set the drums bus to NO OUTPUT. This allows me to use the sends on the drums bus channel to split the frequencies. I create 2 sends and have them both at the same level - 0.0 in the case of logic. I send to 2 different buses I label Mono and Stereo. On the Mono bus I use only Logics Multipressor and Solo the first frequency band and set the band to range from 0 to about 300 HZ. I make sure the Mono bus is also actually operating in MONO lolzzzzzzzz Then basically just do the opposite for the stereo- multipressor, solo all the bands above 300 hz and operate in stereo. Anyone got any other interesting methods?
