pianoroll-generator

Pianoroll-generator A package to generate pianoroll (NPZ) datasets

Getting Started

---

1. Building from the source

   • First clone the repository to your local directory with git

   • Open your local Terminal/Command Shell and run the following commands:

     cd pianoroll-generator # change directory to the cloned repository
     #use any of the following some will work dependent on your operating system
     #try
     python3 setup.py develop # works on both osx and linux
     #or
     pip install . 

   Usage

   • TO GENERATE A DENSE NPZ DATASET, first Download some midi files and place them in the midis directory

   Note the midis is an arbitrary dir, it can be named A anything

   • On either your python terminal or idle shell run the following codes:

   1. To create a list of files with common tracks

      python inference.py -t 'Your specified number of tracks'

      The default mode is processing the list of midi files

   2. To now generate the dense dataset run the following code set the inference mode to parsing

       python inference.py --mode 'parse' 

   3. Run help:

      python inference.py --help

      returns:

      usage: inference.py [-h] [-i FILEPATH] [-t TRACKS] [-o OUTPUT] [--mode MODE]
      options:
       -h, --help            show this help message and exit
       -i FILEPATH, --filepath FILEPATH
                             Path to your midi files.
       -t TRACKS, --tracks TRACKS
                             Number of tracks.
       -o OUTPUT, --output OUTPUT
                             output fname of your pianoroll.
       --mode MODE           mode processing or parsing.

TODO

1. command line arguments with user defined inputs
2. Add support for own track checking from list of midis
3. PYPI (cancelled)
