Looks awesome, love the tab view.

If there other hackers who make music here, I wrote this:

https://github.com/Miserlou/chords2midi

for writing chord progressions on the command line. I use it for building progressions which I drag into my DAW. It has voice leading, which required me translating an algorithm from 18th century German musical textbook into Python. I don't speak German and there were no unit tests in the 1700s so I'm only fairly certain that it works properly.

I will make a plugin version once ableton supports CLAP.

Awesome! Please do a Show HN when the plugin is done.

This looks really awesome! Do you know https://www.mellowood.ca/mma/ and if yes, do you mind doing a short feature comparison?

Wow, never seen that before. This seems more like a whole plaintext musical language, like mma is to midi what markdown is to HTML. Mine is just a way for somebody in a hurry to get the MIDI chords they want without putting all of the notes in manually.

"Gradus ad Parnassum" by Johann Joseph Fux, right?

Read it a couple of years ago after learning basic music theory, as I was still struggling to write consonant voices.

I probably wasn't the first person to think that contrapunctual rules might lend themselves to algorithmic implementation - so it's very cool to see you've done just that in your project!

They didn’t have unit tests in 1700, but I’m pretty sure that Max for Live was popular around that time.
