You have probably watched plenty of videos about grouping drums. The fact of it is this: grouping drums allows you to then process all the individual drum sounds as one whole sound.
Similarly to compression once you have made your groups you can then EQ the group as a whole.
There is no right or wrong way to group your drums, I know some artists who group every single drum or percussion sound together, and I know others who like to separate these groups, I.e. one group for the hats, one group for the percussions, one group for all clap sounds and a kick drum group (if they have layered different sounds to build a kick).
My approach to every track is different. Some of my tracks I may use all of the drum sounds ‘as one’, and other times I make a kick group, clap / snare group and a hats/percussion group. It really depends on HOW you want to treat all the sounds. Remember the outcome is how good it SOUNDS, do not get caught up in the routine of it all……..sometimes you can trick yourself into believing that every track you produce needs to be made in exactly the same way. Having said that, it is beneficial to set up templates where selected channels are already routed and grouped together, however; don’t feel like you need to use the same procedure every track.
Experiment with processing individual sounds and processing the groups. In dance music, a lot of focus is on the kick and snare. If you start with original samples which are of high quality then this minimizes the processing which you need to apply. In some cases you will barely need to process them, maybe add EQ or some slight compression but sometimes you may not need any processing. As i learn more i find myself using good kick samples and not doing any processing on it.
f you are grouping things together then you want to make use of a good buss compressor - i tend to use Cytomic 'the glue' compressor.
Remember that processing a group can save your CPU usage, so if you are going to apply similar reverbs to a lot of sounds, then why not group them together and treat that group with only one reverb instead of using numerous reverb plug-ins? When you are operating with samples, keep in mind that if the original sample is bad quality, then grouping them and processing them will not make them sound better, you may get the sound a little cleaner but trying to touch up bad samples is not a route you want to take. It is time consuming and in most cases, unnecessary.
So there you go! The benefits of using a buss: less CPU usage, makes sounds more cohesive, treat a whole group of sounds ‘as one’, can apply an effect to a whole range of sounds rather than using multiple individual plug-ins, they are all on one fader making the overall volume of the group easy to handle and finally it just tidies up your projects. Make use of colour coding to make it easier to follow.
