Routing a sine wave through a bitcrusher at 8-bit depth creates grime's characteristic lo-fi buzzy bass

One of grime’s signature bass textures — the buzzy, degraded bass heard on MIA’s ‘Bucky Done Gun’ and numerous grime tracks — is achieved by processing a simple sine wave through a bitcrusher (bit-depth reducer) set to 8 bits. This folds the smooth waveform into a harsh, quantised approximation, producing a buzzy distortion with distinctly lo-fi, early-hardware character. Setting the synthesiser’s pitchbend range to ±1 octave and using the pitch wheel during playback adds the idiosyncratic pitch-slide quality. This is essentially 8-bit chiptune aesthetic applied to bass design within a grime context.

Examples

MIA — ‘Bucky Done Gun’ as the canonical reference. Tip 12: ‘route a simple sine synth sound through a degrader plug-in - a setting of 8 bits will give you a none-too subtle effect. Set your synth’s pitchbend range to plus/minus an octave and get busy with your keyboard’s bend wheel for that idiosyncratic lo-fi bass ride.‘

Assessment

In a synthesiser, create a sine wave bass. Route it through a bitcrusher. Compare 16-bit, 12-bit, 8-bit, and 4-bit settings and describe the timbral change at each step. Then add pitchbend and identify the grime bass character.
