Python library to generate guitar tabs from MIDI files
# Install globaly
$ pip install tayuya
# Install only for the current user
$ pip install --user tayuya
>>> from tayuya import MIDIParser
>>> mid = MIDIParser('sample.mid', track=0)
>>> print(mid.render_tabs())
E-------------14--------------------------16--14----------14--------------
A-------------------------------------------------17--17------16--17--16--
D-16------16------16--16--16--16------16----------------------------------
G-----18--------------------------18--------------------------------------
B-------------------------------------------------------------------------
E-------------------------------------------------------------------------
Don't forget to set the track
argument with the appropriate track number desired.
>>> from tayuya import MIDIParser
>>> mid = MIDIParser('sample.mid', track=0)
>>> mid.get_tracks()
{0: 'Lead Guitar',
1: 'Rhthym Guitar Dist',
2: 'Acoustic Guitar',
3: 'Rhthym Guitar Clean & Dist',
4: 'Lead Guitar Fill',
5: 'Guitar Harmonics',
>>> mid = MIDIParser('sample.mid', track=0)
>>> mid.notes_played()
[{'note': 'C#5', 'time': 18},
{'note': 'C#5', 'time': 30},
{'note': 'B4', 'time': 26},
{'note': 'C5', 'time': 0},
{'note': 'C5', 'time': 28},
{'note': 'C#5', 'time': 28},
{'note': 'C#5', 'time': 30}]
>>> mid = MIDIParser('sample.mid', track=0)
>>> mid.get_key()
You can use this example to generate all the notes to play with their string and fret positions.
>>> mid = MIDIParser('sample.mid', track=0)
>>> tabs = Tabs(notes=mid.notes_played(), key=mid.get_key())
>>> tabs.generate_notes(tabs.find_start())
[('C#3', 5, 4),
('G#3', 4, 6),
('C#4', 3, 6),
('F4', 2, 6),
('B2', 6, 7),
('D#3', 5, 6),
('F#3', 4, 4),
('B3', 3, 4),
('D#4', 3, 8),
('F#2', 6, 2)]
Each tuple here is (note, string, fret)
Here's a brief of how it works:
- Fetch a track from the MIDI file
- Find all the notes played and convert from MIDI code values to music notes
- Find a scale for the set of notes extracted
- Find the best position to play the extracted notes using the scale detected
- Works only for guitar solos. Implementation for determination and rendering of chords is not done yet.
- Works only for standard tuning (E A D G B E)
- Render tabs using Lilypond or some GUI alternative
- Implement logic to determine and render chords
- Better the scale detection implementation
- Transposing
- Add way to handle non standard tuning
- More stringed instruments
