MusicXML-Synthesizer

This program is still under development and test.

A program can convert solola results to musicXML(.musicxml) format

[Solola results] => MusicXML-Synthesizer => [musicxml format file]

Note: We will set MuseScore and Tux Guitar as validation editor. It means that MusicXML-Synthesizer will ensure both of editor can successfully open output.

Requirements

• pipenv
• other dependencies check out Pipfile

Usage

# basic 
python cli.py [-s SOLOLA_PATH] [-db DOWNBEAT_PATH] [-b BEAT_PATH]
              [-o OUTPUT_PATH] [-x EXECTUE_VALIDATION]

python cli.py -s /e/workplace/projects/solola/MusicXML-Synthesizer/input_mock/bend/FinalNotes.txt -db /e/workplace/projects/solola/MusicXML-Synthesizer/input_mock/bend/downbeats.txt -b /e/workplace/projects/solola/MusicXML-Synthesizer/input_mock/bend/beats.txt -o outputs/test/test.musicxml

# detail
python cli.py -h

# example
solola_list = parse_notes_meta_to_list(
      solola_path)
beats_list = parse_notes_meta_to_list(
      beat_path)
downbeats_list = parse_notes_meta_to_list(
      downbeat_path)

output_path = './output.mzxml'

# setup
synthesizer = Synthesizer()
synthesizer.save(solola_list, downbeats_list, beats_list)

# synthesize musicXML
xml = synthesizer.execute(output_path)

# create folder and write file to file system
write_file(output_path, xml)

Test

We use pytest and pytest-watch. Use ptw command in director root

# pytest show verbose & print
pytest -s -v

# pytest watch
ptw . -- -vvv

# coverage
python -m pytest tests -s -v --cov=./

# run single test case
ptw tests/test_unit_Synthesizer.py  -- -k 'test_Synthesizer_annotate_rest_and_tech
nique' -vvv --cov=./

value

• Pit: pitch (MIDI number)

• On: onset (sec.)

• Dur: duration (sec.)

• PreB: pre-bend

  - 0 for none,
  - 1 for bend by 1 semitone,
  - 2 for bend by 2 semitone,
  - 3 for bend by 3 semitone
  

• B: string bend

  - 0 for none,
  - 1 for bend by 1 semitone,
  - 2 for bend by 2 semitone,
  - 3 for bend by 3 semitone
  

• R: release

  - 0: none, 
  - 1: release by 1 semitone,
  - 2: release by 2 semitone,
  - 3: release by 3 semitone
  

• P: pull-off

  - 0: none, 
  - 1: pull-off start,
  - 2: pull-off stop
  

• H: hammer-on

  - 0: none,
  - 1: hammer-on start,
  - 2: hammer-on stop
  

• S: legato slide

  - 0: none,
  - 1: legato slide start, 
  - 2: legato slide stop
  

• SI: slide in

  - 0: none,
  - 1: slide in from below,
  - 2: slide in from above
  

• SO: slide out

  - 0: none,
  - 1: slide out downward,
  

• V: - 0: none - 1 for vibrato: vibrato with extent smaller or equal to 1 semitone, - 2 for wild vibrato: vibrato with extent larger than 1 semitone
