Make Your Beats Stand Out!
When dealing with a stagnant beat that could use some added flavor, try routing the individual elements (kick, snare, hats) to different processors and then remixing them together. The process is simple and rewarding…
If the drum mix is already split into separate tracks, as in most ProTools sessions, just adjust the outputs to different aux inputs and add your desired effects. After you are happy with the new effects, route the individual aux outputs to a stereo aux input and fine tune the new drum mix composite with some EQ, compression / whatever is needed. You can even add this new mix under or over the dry mix, panned to opposite sides, etc. to see what happens.
However, if you are using Reason and have a rex file, try using the NN-XT. After loading your drum sample, 
open the NN-XT Editor panel and highlight a drum element from the step sequenced graphic. On the far right, middle of the screen, there is the “out” rotary knob which allows you to send each piece of the highlighted drum beat to its own output channel. You can now route as many effects as you want from these new outputs or use the NN-XT Editor panel to alter your sounds. By incorporating Reason’s Spider merger/splitter, the routing possibilities from the NN-XT to other soft-gear are pretty much endless (Try distortions, delays, filters, phasers, reverbs or some crazy EQing…). After your effects processing sounds good, route the separate outputs to a “drum bus” Line Mix and send the Line Mix output to a single channel in the song mixer. Now Booyah!, your drum mix is vastly different and more dynamic than ever before!
