los-angeles-midi-dataset's Issues

Unable to locate the 'ticks' parameter in the metadata

Thank you so much for this dataset. I'm currently exploring and playing around with it, however I think I may be missing something very basic here.

I used the unpacked meta_data from here
meta_data = pickle.load(open('/home/s_ani/home/datasets_lemo/LA_midi/Los-Angeles-MIDI-Dataset/META-DATA/LAMDa_META_DATA.pickle', 'rb'))

And when I check for one MIDI, I couldn't find the 'ticks' required by the opus2midi function from MIDI.py:

def opus2midi(opus=[]):
    r'''The argument is a list: the first item in the list is the "ticks"
parameter, the others are the tracks. Each track is a list
of midi-events, and each event is itself a list; see above.
opus2midi() returns a bytestring of the MIDI, which can then be
written either to a file opened in binary mode (mode='wb'),
or to stdout by means of:   sys.stdout.buffer.write()

The only information I do have is set_tempo, and I'm wondering how to come up with the 'ticks' parameter. I hope to thereafter write out like a MIDI file. Maybe this is not the intended way to load and use this dataset, or maybe I'm missing some understanding of the 'ticks' concept. Any help/suggestions would be very helpful!

Thanks.

Where do the chords come from?

Did you automatically extract/predict them? If so, how?

Do you have a paper or report that you can share, on how you collected the data etc?
