A SuperDirt sample name must match a dirt-samples folder; sound "kick" is silent because the folder is bd
SuperDirt loads audio from folder names in the dirt-samples set, which use short abbreviations: bd for bass drum (kick), sn for snare, hh for hi-hat. sound “kick” is silent because no folder named kick exists — the correct name is sound “bd”. A :index out of range for a folder likewise falls back to silence. So a silent voice with valid-looking syntax is usually a sample-name (or index) that does not exist in the loaded bank; validate names against the shared samples list.
Examples
— Wrong (silent, no such folder): d1 $ sound “kick” — Correct: d1 $ sound “bd”
Assessment
Why does d1 $ sound “kick” produce silence in SuperDirt, and what is the correct sample name for a kick?
