The script converts general midi drum patterns (which can be found easily online) to hydrogen pattern format. When installed to the hydrogen patterns directory (usually '~/.hydrogen/data/patterns') the patterns are automaticcaly imported to the hydrogen library.

The script requires the python_midi library which can be installed through pip:

pip install git+https://github.com/vishnubob/python-midi@feature/python3

The script accepts four parameters: the input filename, the output filename, the category (as it appears in the hydrogen library), the name (as it appears in the hydrogen library)

python midi2hydro_pattern.py "my_midi_file.mid" "my_h2_pattern.h2pattern" "pattern_genre" "pattern_name"

If only the input filename is provided, the other parameters will be created from it.

python midi2hydro_pattern.py "my_midi_file.mid"
