About

A set of Python scripts for building OP-XY multisample instruments. One records multisamples automatically from any MIDI instrument (or a DAW on a Mac); others name the files to the OP-XY's conventions, generate the preset JSON, and pack everything into the folder structure the OP-XY expects. It's one of the early projects built on reverse-engineering the OP-XY's multisample format.
