mf-utils
developmentgithub
mf-utils is a Python toolkit for working with Arturia MicroFreak firmware files and their embedded wavetables. Its wavetabula command-line tool extracts tables to WAV files, replaces them with edited audio and smooths waveforms to reduce clicks and other artifacts. The repository also provides libraries for reading and writing MicroFreak firmware and wavetable data. It produces modified firmware files for use with Arturia’s MIDI Control Center; flashing those files can damage the instrument or affect its warranty. The toolkit supports 16-bit mono WAV files in the MicroFreak’s expected wavetable layout.
