Running a metallic percussive output through a granular engine adds a sustained noisy texture to a minimal techno patch

The metal output of a hi-hat module produces broadband metallic noise bursts. Feeding this into a granular engine (e.g. Supercell in granular mode) with high feedback, high space/panning, short grain size, and random grain-size modulation creates a sustained ambient noise pad derived from the rhythmic hits. Shape turned fully left generates snappy grains; density controls how continuously grains fire. This transforms transient percussion into an atmospheric background layer, adding textural depth without an extra oscillator or sampler.

Examples

VCV Rack: hi-hat metal output -> Supercell (Grayscale, granular mode), feedback up, shape left, small grain size, internal random modulation on size -> mixer send.

Assessment

Explain why taking the metal output of a hi-hat module rather than the audio output produces a different granular texture, and describe two Supercell parameters you would adjust to shift it from ‘background noise’ to ‘melodic drone’.
