They keep an electronic kick and snare in Serum inside their default template. Having the drums in a live state allows them to be sculpted to suit the needs of each project.
It is best to bounce kicks with a long tail, then shape them as needed. You can remove a tail, but can't easily add one.
Uses Kick 2 (Sonic Academy) to make their kick drums.
MV: Noisia and Mr Bill also use the Kick 2 plugin. It allows for greater control over the shaping and tonality of the sound when compared to Serum.
The key for making kick drums is getting the nodes into the right place within the Kick 2 interface. The plugin also provides the key information for each node, making tuning a breeze.
If you extend the first node, dragging it to the right in Kick 2, you'll get a deeper sounding kick drum. Less of a sharp transient, but more body, which may or may not be what you're looking for.
You can high-pass 'tone' or foley noise, to sit-on-top of the kick to give it added high-end presence.
MV: Many producers layer in a hat on a kick for the same reason.
Crafting drums from scratch is tedious but rewarding work. If you focus on the nitty-gritty details from the beginning, you'll have a much better time working on a track as you won't have to force the mix. The sounds and instruments should come together with relative ease as you've shaped them to each form a symbiotic connection.
