Tech house sub bass roll, 124bpm, 4 bars

About this sample

This sub bass roll features a clean sine wave at 49 Hz, creating a deep and pure low end. It plays a rolling rhythm with notes on the 3rd and 4th sixteenth notes of each beat at 124 BPM, avoiding the downbeat to leave space for the kick. Each note has a quick 5 ms attack and a smooth decay, with sidechain-style volume ducking on each quarter note for a pumping effect. The sound is filtered with a low-pass at 120 Hz and a high-pass at 25 Hz to keep it tight, with gentle tanh saturation adding subtle harmonics and presence.

It suits tech house and similar genres around 124 BPM, providing a solid, rhythmic sub foundation. The mono bass can be layered under kicks and percussive elements, and its pumping sidechain helps maintain clarity. Watch for low-end buildup if layering multiple basses, and consider additional EQ to fit your mix’s sub range.
