Dub techno sub bass is made from the kick sample by cutting its transient and keeping only the subby tail

A common dub techno move builds the sub bass from the kick itself: copy the kick channel and move it off the beat, then cut the first, aggressive part of the sample off so only the subby tail remains. Filter it further to keep just the lows, add delay to keep it rhythmical, and add reverb to smear the sustain — turning the reverb’s Stereo down so the bass stays mono and focused. A drum buss can glue it before a final low filter. Because sub and kick share a sample origin they are spectrally related, which reduces phase problems and simplifies gain staging compared with an unrelated sub oscillator.

Examples

Ableton: duplicate kick channel → set sample start past the transient → LPF to sub only → mono reverb (Stereo = 0) → delay for rhythm → nudge MIDI off the beat.

Assessment

Explain why deriving the sub from the kick tail reduces low-frequency problems versus an independent sub oscillator, and describe what ‘cutting the transient’ means in terms of the sample start point.
