The final two elements to add to the main riff are a kick drum on each crotchet beat (four to thefloor) and a noise blast at the start of every second bar. Use a kick that has a nice amount of low but plenty of click in order to cut through. Compress it quite severely in order to make it bounce with the track and cut through the synth riffs.
Experiment with the enveloper plug-in, or a gate to get the correct kick length. Also add some reverb and roll out any unnecessary low-end on the Eq. In order to make the noise blast, I’ve used Logic’s ESP Noise generator with a long Decay, Sustain and Release and fast Attack, with the filter frequency set to about a quarter open. I’ve also added a reverb plug-in to help blend the noise with the track nicely. To finish off, add some Eq across the mix, as the original is very high-mid heavy. I’ve boosted +6.5dB @3.5kHz, +2dB @2kHz and +3.5dB @1060Hz.
