  • Music theory/helper apps?
    Some of the other similar products I've looked at are Instachord and Cthulhu. Source: 10 months ago
  • Arpeggiating chords randomly and in sequence
    Ok. I don't think you can do this in Live natively, Your best bet is probably a vst plugin like https://www.kirnuarp.com/ or https://xferrecords.com/products/cthulhu. Source: over 1 year ago
  • Help pleaseee producers🙏 How can I make a similar sounding arp in Diva U-he
    There are lots of arpeggiators built into synths, but one I really like - and one that should be able to do this for you - is Xfer Cthulhu. I looked briefly at FL's own offerings but I don't think they're realtime - i.e. you're supposed to program it and then it draws notes in the piano roll for you. Source: over 1 year ago
  • Arpeggiator Effect plug-ins?
    Https://xferrecords.com/products/cthulhu still going strong, and the chord memory is really nice. Source: about 2 years ago

  • A smart way to translate guitar chords into piano sheet music with Python
    I chose Python as a programming language here because, as you could probably guess, there are myriads of libraries in Python for working with music. I found mingus to be the simplest for working with guitar chords and music21 for generating the piano score. It might be possible though to do everything with music21 only, because it's extremely powerful, but I found mixing the two libraries to be easier than... - Source: dev.to / about 1 year ago

    If you are interested in doing anything with Python, be sure to check out Music21, which has a lot of cool features — including doing twelve-tone matrix stuff like this — built-in. Source: about 1 year ago

  • [D] Is MusicGPT a viable possibility?
    It's definitely a viable possiblity, and there's quite a few companeis already doing it. If you want to explore doing it yourself, I'd check out https://web.mit.edu/music21/ and build some basic models using LSTM etc. To have some fun using open source MIDI data sets like https://magenta.tensorflow.org/datasets/maestro .

  • Ask HN: Is there a OS tool which queries MIDI datasets by chord progression/key?
    A little manual, but music21[0] can do the analysis! [0]: http://web.mit.edu/music21/. - Source: Hacker News / over 1 year ago
