In my productions drums are one of the most important elements, if not the most important besides the vocals that will be recorded later...because of this, I often spend a lot of time getting my drums to sound just right. Whether it be sample selection, tuning, or groove - they all play a massive roll in getting my drum tracks to bang right.
When starting a beat, I dont worry too much about the mix or the effects that I use, (even dynamic processing isnt a concern at this stage, unless I simply need to bring up the relative level of my drums in order to even hear them correctly while i sequence)...
At this point, its all about bringing a concept into reality and creating something to build off of. This often changes later as well once the song begins to take form.
(1) So first thing I focus on I suppose would be drum selection.
The drums need to always appropriately accompany the mood, the sample, the instrument choices, etc. Ive found that if I fall short in that area, then the rest of the song doesnt come together as it should usually.
(2) Next, its on to sequencing. I lace up the basic kick snare hat structure so that I have a basic building block. (Note: I usually build my drums around a main sample or melody line since I find my songs to be more cohesive that way and not like two different instruments are fighting for attention in the mix, ie. drums vs sample)
(3) Once a basic pattern is working, I focus primarily on groove. I asses whether or not I like how the groove feels and if I need to re-record it now to offer a different swing, etc. Sometimes its just a matter of time shifting, I often find its better to just re-record the sequence though to capture the real feel Im after.
(4) Next I lace up my percussion. Im really big on percussion so I always like to add an entirely new layer of percussive sounds to help amend the track in a way that another instrument would basically.
(5) At this point the drums are typically done minus some sequence swapping and mute automation's...
(6) Since I sequence on the MPC, I dont bother using effects usually until I track into my DAW. So things like compression usually dont come into play until I have everything tracked out and Im at the stage where Im ready to mix the entire beat down. (I have been using a mild ratio of compression from the MPC lately however in order to just clamp down on the transients peaks a little to help tame some of the spikes and make the conversion into the computer go a little more smoothly.)
And thats about it!
