        "description": "Unroll\n=======\n\nUnroll is a Python module to ease transcription of piano rolls to sheet music.\nIt transcribes either a MIDI file or a video of a piano roll. It finds\nthe notes, the tempo, roughly separates the hands, and writes the result\nin a Lilypond file. In particular\n\nYou can use it like this: ::\n    \n    # TO TRANSCRIBE FROM A VIDEO\n    \n    from unroll import video2scan, rollscan2keystrikes\n    focus = lambda im : im[[156],58:478]\n    scan = video2scan(videofile = \"limehouse_nights.mp4\", focus = focus)\n    keystrikes = rollscan2keystrikes(scan)\n    keystrikes = ks.transposed(26)\n    keystrikes.transcribe('score.ly', quarter_durations = [2,10,0.02])\n    \n    # TO TRANSCRIBE FROM A MIDI FILE\n    \n    from unroll import midi2keystrikes\n    keystrikes = midi2keystrikes('tiger_rag.mid')\n    ks.transcribe('score.ly', quarter_durations = [50,100,0.02])\n\n\nThen you must edit ``score.ly`` to correct the mistakes and when you are done you compile it with\n::\n    \n    lilypond score.ly\n    \n    \nInstallation\n--------------\n\nUnroll can be installed by unzipping the source code in one directory and using this command:\n::\n    \n    (sudo) python setup.py install\n\nYou can also install it directly from the Python Package Index (PYPI_) with this command:\n::\n        \n    (sudo) pip unroll install\n\n\nContribute\n-----------\nUnroll is an open-source software originally written by Zulko_ and released under the MIT licence.\nThe project is hosted on Github_ and everyone is welcome to contribute ! Please give feedback if you are using it and encounter difficulties.\n\n\n.. _PYPI: https://pypi.python.org/pypi/unroll\n.. _Github: https://github.com/Zulko/Unroll\n.. _Zulko : https://github.com/Zulko",
