About

A Python script that turns a library of one-shot samples into OP-1 field drum kits (.aif drum patches), making one kit per folder with each sound matched to its named key. Hats are choke-grouped, headroom is adjustable (default -3 dB), and each kit comes with a text file mapping key to sample. It writes the files directly, matching what the web drum-utility exports byte for byte, so no browser round trip is needed.
