About

A command-line tool for building and changing OP-1 and OP-Z patches without touching the device. It can copy samples from one set of keys to another, create a drum patch from up to 24 WAV files, dump the OP metadata stored in a patch and create patches in batches. It installs from a release download (the macOS build is the one shown) or builds from source.
