The grime eskibeat bass is built from a pulse oscillator, slow amp envelope, mono glide, low-pass filter, and unison detune

The foundational grime bass — popularised by Wiley in the early 2000s and tied to the eskibeat sub-genre — is assembled from five interdependent elements: (1) a pure pulse-wave oscillator for harmonic-rich content; (2) a slow amplitude attack and release for a lazy, swooping feel rather than a punchy transient; (3) monophonic voicing with short glide, enabling pitch slides between notes; (4) a low-pass filter at mid cutoff with minimal resonance, murking the bright pulse into the low end; and (5) unison detune (about 3 voices, moderate spread) for beating and ‘filth’. The recipe reproduces on any virtual-analogue synth. The steps are ordered: glide requires mono voicing, and unison only matters after the filter has shaped the brightness.

Examples

In Massive (or any VA synth): init patch; Osc 1 Wt-position fully down (pure pulse); 4 Env Attack ~10 o’clock, Release ~11 o’clock; Voicing Monophon, Glide Time ~10-11 o’clock; Filter 1 Lowpass 2, Cutoff 12 o’clock, Resonance minimum; Unisono Spread on Pitch+Cutoff at 0.20 with 3 voices. Play a slow minor phrase with slides.

Assessment

Build this patch from scratch on any VA synth. Identify which element most produces the ‘swoop’ and which most produces the ‘filth’. Change one parameter at a time and describe the effect. Explain why mono voicing is needed for glide.
