What Hacker News says
6 sourcesLooks 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.
In Coltrane: A music theory library with a command-line interfaceI ended up creating a lighter version of this for one my projects, https://github.com/Miserlou/chords2midi
I think that something that Alda looks like it lacks right now is doing things around intervals rather than notes, as transpositions and key changes will be very tedious without embedded knowledge of intervals.
My project is based around a Python library called Mingus, which I think gives you most of what you'd ever need to build a music programming project.

In Alda – Text-Based Programming Language for Music CompositionThis is cool, I made a similar command line tool for generating the same sort of thing:

Demo: https://clyp.it/f0g1ko5b
In Ask HN: Do you create music? let's hear itThis is cool!
I've build a much cruder version that I use for generating chord sequences to bring into DAWS:
https://github.com/Miserlou/chords2midi
It even has voice leading, which required translating an "algorithm" written in German in the 1800's!
In Show HN: Warp, a Python based music-theory aware MIDI sequencerFunnily enough, I spend the weekend making almost the exact opposite of this:
